Forest Hill, MD, Nov. 15, 2016 (GLOBE NEWSWIRE) -- The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 350 Open Source projects and initiatives, announced today the availability of Apache® jclouds™ v2.0, the Java multi-cloud toolkit.
Apache jclouds gives users the freedom to create applications that are portable across clouds while providing full control to use cloud-specific features. As a cloud-agnostic library, jclouds enables developers to access a variety of supported cloud providers using one API.
"Apache jclouds 2.0 represents a significant milestone for the project" said Ignasi Barrera, Vice President of Apache jclouds. "We are proud to support all major cloud providers in the marketplace with a mature, stable, codebase that is ready for production."
jclouds entered the Apache Incubator in April 2013 and graduated as a Top-Level Project (TLP) in October of the same year. The Apache jclouds 2.0 release is the 11th release as a TLP and the consolidation of the project, with more than 13K commits (1K in the last release) made by more than 250 contributors (35 new last year).
Under The HoodApache jclouds 2.0 features include:
Apache jclouds is used by Abiquo, Adobe, CloudBees, Cloudify, Cloudsoft, Mesosphere, and RedHat, among many others. In addition, jclouds is supported by cloud companies and communities such as Amazon Web Services, Backblaze B2, Apache CloudStack, Docker, Google Cloud Platform, Microsoft Azure, OpenStack, Rackspace, and many more.
"Abiquo, as the creator of the leading commercial cloud management platform, relies on jclouds to give their customers the agility they need," said Ian Finlay, CEO of Abiquo. "Using jclouds and their plugin architecture they have been able to deliver support for new cloud providers and features demanded by their customers in days or weeks rather than months. This approach ensures that their service provider and enterprise customers can bring together the cloud providers they need to deliver a great hybrid cloud solution to their customers."
"Apache jclouds provides Cloudsoft AMP with a layer of abstraction across clouds allowing Cloudsoft AMP to model, deploy and manage applications in line with their customers’ requirements," said Duncan Johnston-Watt, Founder and CEO of Cloudsoft. "Many of their customers have multi-cloud application strategies and need rapid support for target locations as these emerge. I’m pleased to see support Microsoft Azure Resource Manager and improvements for OpenStack (Mitaka) and IBM cloud targets."
"We are very proud of their achievement and welcome contributions that help grow the Apache jclouds community, including joining their mailing lists and submitting feedback, use cases, bug reports, patches, and documentation," added Barrera.

All this means that with PCF, your build artifact is your native deployment artifact, while in Kubernetes your build artifact is a docker image. With Kubernetes, you need to define the template for this docker image yourself in a Dockerfile, while in PCF you get this template automatically from a buildpack.Management Console Cloud Foundry
PCF separates the web dashboard to two separate target audiences.
Kubernetes takes a different approach. You get one dashboard to manage everything. Here’s a typical Kubernetes dashboard:
As you can see from the left-hand side, there is a lot of data to process here. You have access to persistent volumes, daemons, definition of roles, replication controllers etc. It’s hard to focus on what are the developer’s needs and what are the IT needs. Some might tell you this is the same person in a Devops culture, and that’s a fair point. Still, in reality-it is a more confusing paradigm compared to a simple application manager.Command Line Interface Cloud Foundry
Cloud foundry uses a command line interface called cf. It is a cli that lets you control all aspects of the developer interaction. Following in the footsteps of simplicity that you might have already noticed, the idea is to take an opinionated view to practically everything.
For example, if you are in a folder that contains a spring boot jar file called myapp.jar, you can deploy this application to PCF with the following command:cf push myapp -p myapp.jar
That’s it! That’s all you need. PCF will lookup the current working directory and find the jar executable. It will then update bits to the platform, where the java buildpack would create a container, calculate the required memory settings, deploy it to the currently logged-in org and space in PCF, and set a route based on the application name:wabelhlp0655019:test odedia$ cf push myapp -p myapp.jar Updating app myapp in org OdedShopen / space production as user… OK Uploading myapp… Uploading app files from: /var/folders/_9/wrmt9t3915lczl7rf5spppl597l2l9/T/unzipped-app271943002 Uploading 977.4K, 148 files Done uploading OK Starting app myapp in org OdedShopen / space production as user…Downloading pcc_php_buildpack…Downloading binary_buildpack…Downloading python_buildpack…Downloading staticfile_buildpack…Downloading java_buildpack…Downloaded binary_buildpack (61.6K)Downloading ruby_buildpack…Downloaded ruby_buildpackDownloading nodejs_buildpack…Downloaded pcc_php_buildpack (951.7K)Downloading go_buildpack…Downloaded staticfile_buildpack (7.7M)Downloading ibm-websphere-liberty-buildpack…Downloaded nodejs_buildpack (111.6M)Downloaded ibm-websphere-liberty-buildpack (178.4M)Downloaded java_buildpack (224.8M)Downloading php_buildpack…Downloading dotnet_core_buildpack…Downloaded python_buildpack (341.6M)Downloaded go_buildpack (415.1M)Downloaded php_buildpack (341.7M)Downloaded dotnet_core_buildpack (919.8M)Creating containerSuccessfully created containerDownloading app package…Downloaded app package (40.7M)Staging…— — -> Java Buildpack Version: v3.18 |https://github.com/cloudfoundry/java-buildpack.git#841ecb2— — -> Downloading Open Jdk JRE 1.8.0_131 from https://java-buildpack.cloudfoundry.org/openjdk/trusty/x86_64/openjdk-1.8.0_131.tar.gz (found in cache)Expanding Open Jdk JRE to .java-buildpack/open_jdk_jre (1.1s)— — -> Downloading Open JDK Like Memory Calculator 2.0.2_RELEASE from https://java-buildpack.cloudfoundry.org/memory-calculator/trusty/x86_64/memory-calculator-2.0.2_RELEASE.tar.gz (found in cache)Memory Settings: -Xmx681574K -XX:MaxMetaspaceSize=104857K -Xss349K -Xms681574K -XX:MetaspaceSize=104857K — — -> Downloading Container Security Provider 1.5.0_RELEASE from https://java-buildpack.cloudfoundry.org/container-security-provider/container-security-provider-1.5.0_RELEASE.jar (found in cache) — — -> Downloading Spring Auto Reconfiguration 1.11.0_RELEASE from https://java-buildpack.cloudfoundry.org/auto-reconfiguration/auto-reconfiguration-1.11.0_RELEASE.jar (found in cache) Exit status 0Uploading droplet, build artifacts cache…Uploading build artifacts cache…Uploading droplet…Staging completeUploaded build artifacts cache (109B)Uploaded droplet (86.2M)Uploading completeDestroying containerSuccessfully destroyed container0 of 1 instances running, 1 starting0 of 1 instances running, 1 starting0 of 1 instances running, 1 starting0 of 1 instances running, 1 starting1 of 1 instances running
Although you can start with barely any intervention, this doesn’t mean you give up any control. You have a lot of customizations available in PCF. You can define your own routes, set the number of instances, max memory and disk space, environment variables etc. All of this can be done in the cf cli or by having a manifest.yml file available as a parameter to the cf push command. A typical manifest.yml file can be as simple as the following:applications:- name: my-appmemory: 512Minstances: 2env:PARAM1: PARAM1VALUEPARAM2: PARAM2VALUE
The main takeaway is this: with PCF, provide the information you know, and the platform will imply the rest. Cloud Foundry’s haiku is:
Here’s my code
Run it on the cloud for me.
I don’t care how.Kubernetes
In kubernetes, you interact with the kubectl cli. The commands are not complicated at all, but there is still a higher learning curve from what I’ve experienced so far.
For starters, a basic assumption is that you have a private docker registry available and configured (unless you only plan to deploy images available on public registries such as docker hub). Once you have that registry up and running, you will need to push your Docker image to that registry.
Now that the registry contains your image, you can initiate commands to kubectl to deploy the image. Kubernetes documentaiotn gives the example of starting up an nginx server:# start the pod running nginx$ kubectl run --image=nginx nginx-app --port=80 --env="DOMAIN=cluster"deployment "nginx-app" created
The above command only spins up a kubernetes pod and runs the container.
A pod is an abstraction that groups one or more containers to the same network ip and storage. It’s actually the smallest deployable unit available in Kubernetes. You can’t access a docker container directly, you only access its pod. Usually, a pod would contain a single docker container, but you can run more. For example, an application container might want to have some monitoring dameon container in the same pod.
In order to make the container accessible to other pods in the Kubernetes cluster, you need to wrap the pod with a service:# expose a port through with a service$ kubectl expose deployment nginx-app --port=80 --name=nginx-httpservice "nginx-http" exposed
Your container is now accessible inside the kubernetes cluster, but it is still not exposed to the outside world. For that, you need to wrap your service with an ingress.
Note: Ingress is still considered a beta feature!
I could not find a simple command to expose an ingress at this point (please correct me if I’m wrong!). It appears that you must create an ingress descriptor file first, for example:apiVersion: extensions/v1beta1kind: Ingressmetadata:name: test-ingressannotations:ingress.kubernetes.io/rewrite-target: /spec:rules:- http:paths:- path: /testpathbackend:serviceName: testservicePort: 80
Once that file is available, you can create the ingress by issuing a commandkubectl create -f my-ingress.yaml
Note that unlike the single manifest.yml in PCF, the deployment yml files in Kubernetes are separated — there is one for pod creation, one for service creation and as you saw above — one for ingress creation. A typical descriptor file is not entirely overwhelming but I wouldn’t call it the most user friendly either. For example, here’s a descriptor file for nginx deployment:apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2kind: Deploymentmetadata:name: nginx-deploymentlabels:app: nginxspec:replicas: 3selector:matchLabels:app: nginxtemplate:metadata:labels:app: nginxspec:containers:- name: nginximage: nginx:1.7.9ports:- containerPort: 80
All this to say — with kubernetes, you need to be specific. Don’t expect deployments to be implied. If I had to create a haiku for Kubernetes, it’ll be probably something like this:
Here’s my code
I’ll tell you exactly how you should run it on the cloud for me
And don’t you dare make any assumptions on the delployment without my written consent!Zero Downtime Deployments
Both platforms support the ability to deploy applications with zero downtime, however this is one area where Kubernetes wins in my opinion, since it provides a built-in mechanism for zero downtime deployments with rollback.
2019 update: As of Pivotal Cloud Foundry 2.4, native zero-downtime deployments are available out of the box!Cloud Foundry
With Pivotal Cloud Foundry, t̶h̶e̶r̶e̶’̶s̶ ̶n̶o̶ ̶b̶u̶i̶l̶t̶-̶i̶n̶ ̶m̶e̶c̶h̶a̶n̶i̶s̶m̶ ̶t̶o̶ ̶s̶u̶p̶p̶o̶r̶t̶ ̶a̶ ̶r̶o̶l̶l̶i̶n̶g̶ ̶u̶p̶d̶a̶t̶e̶, you’re basically expected to do some cf cli trickery to perform the update with zero downtime. The concept is called blue-green deployment. If I had to explain it in step-by-step guide, it’ll probably be something like this:
Note: The cf cli supports plugin extensions. Some of them provide automated blue-green deployments, such as blue-green-deploy, autopilot and zdd. I personally found blue-green-deploy to be very easy and intuitive, especially due to its support for automated smoke tests as part of the deployment.Kubernetes
kubectl has a built-in support for rolling updates. You basically pass a new docker image for a given deployment, for example:kubectl set image deployments/kubernetes-bootcamp kubernetes-bootcamp=jon/kubernetes-bootcamp:v2
The command above tells kubernetes to perform a rolling update between all pods of the kubernetes-bootcamp deployment from its current image to the new v2 image. During this rollout, your application remains available.
Even more impressive — you can always revert back to the previous version by issuing the undo command:kubectl rollout undo deployments/kubernetes-bootcamp External Load Balancing
As they saw previously, both PCF and Kubernetes provide load balancing for your application instances/pods. Once a route or an ingress is added, your application is exposed to the outside world.
If we’ll take an external view of the levels of abstraction that are needed to reach your application, they can describe them as follows:Kubernetes ingress → service → pod → container Cloud Foundry route → container Internal Load Balancing (Service Discovery) Cloud Foundry
PCF supports two methods of load balancing inside the cluster:
Eureka runs as its own service in the PCF environment. Other applications register themselves with Eureka, thereby publishing themselves to the rest of the cluster. Eureka server maintains a heartbeat health check of all registered clients to keep an up-to-date list of healthy instances.
Registered clients can connect to Eureka and ask for available endpoints based on a service id (the value of spring.application.name in case of Spring Boot applications). Eureka would return a list of all available endpoints, and that’s it. It is up to the client to actually access one of these endpoints. That is usually done using frameworks like Ribbon or Feign for client-side load balancing, but that is an implementation detail of the application, and not related to PCF itself.
Client-side load balancing can theoretically scale better since each client keeps a cache of all available endpoints, and can continue working even if Eureka is temporarily down.
If your application already uses Spring Cloud and the Netflix OSS stack, PCF fits your needs like a glove.Kubernetes
Kubernetes uses DNS resolution to identify other services within the cluster. Inside the same namespace, you can lookup another service by its name. In another namespace, you can lookup the service’s name followed by a dot and then the other namespace.
The major benefit that Kubernetes’ load balancing offers is not requiring any special client libraries. Eureka is mostly targeted at java-based applications (although solutions exist for other languages such as Steeltoe for .NET). With Kubernetes, you can make load-balanced http calls to any Kubernetes service that exposes pods, regardless of the implementation of the client or the server. The load-balancing domain name is simply the name of the service that exposes the pods. For example:
And the API would load-balance over the available instances. It doesn’t matter if your client is written in Java, PHP, Ruby, .NET or any other technology.
2018 update: Pivotal Cloud Foundry now supports polyglot, platform-managed service discovery similar to Kubernetes, using Envoy proxy, apps.internal domain and BOSH DNS.Marketplace
PCF offers a services marketplace. It provides a ridiculously simple way to bind your application to a service. The term service in PCF is not the same as a service in kubernetes. A PCF service binds your application to things like a database, a monitoring tool, a message broker etc. Some example services are:
Third party vendors can implement their own services as well. Some of the vendor offerings include MongoDB Enterprise and Redislabs for Redis in-memory database. Here’s a screenshot of available services on Pivotal Web Services:
IBM Bluemix is another Cloud Foundry provider that offers its own services such as IBM Watson for AI and machine learning applications.
Every service has different plans available based on your SLA needs, such as a small database for development or a highly-available database for a production environment.
Last but not least, you have the option to define user-provided services. These allow you to bind your application to an existing service that you already have, such as an Oracle database or an Apache Kafka message broker. A user provided service is simply a group of key-value pairs that you can then inject into your application as environment variables. This offloads any specific configuration such as URLs, usernames or passwords to the environment itself — services are bound to a given PCF space.Kubernetes
Kubernetes does not offer a marketplace out of the box. There is a service catalog extension that allows for a similar service catalog, however it is still in beta.
Note that since it can run any docker container — Dockerhub can be considered as a kubernetes marketplace in a way. You can basically run anything that can run in a container.
Kubernetes does have a concept similar to user-provided services. Any configuration or environment variables can exist in ConfigMaps, which allow you to externalise configuration artifacts away your container, thus making it more portable.Configuration
Speaking of configuration — One of the features of the Spring Cloud Services service is Spring Cloud Config. It is another service that is targeted specifically for Spring Boot applications. The config service serves configuration artifacts from a git repository of your choosing, and allows for zero-downtime configuration changes. If your Spring beans are annotated with @RefreshScope, they can be reloaded with updated configuration by issuing a POST /refresh API call to your application. The property files that are available as configuration sources are loaded based on a pre-defined loading order, which provides some sort of an inheritance-based mechanism to how the configuration is loaded. It’s a great solution, but again assumes that your applications are based on the Spring Cloud (or .NET Steeltoe) stack. If you’re already using spring boot with a config server today — PCF fits like a glove.
In Kubernetes, you can still run a config server as a container, but that would probably become an unneeded operational overhead since you already have built-in support for ConfigMaps. Use the native solution for the platform you go with.Storage Volumes
A big differentiator of Kubernetes is the ability to attach a storage volume to your container. Kubernetes uses etcd as a means to manage storage volumes, and you can attach such a volume to any of your containers. This means you get a reliable storage solution, which lets you run storage-based containers like a database or a file server.
In PCF, your application is fully stateless. PCF follows the 12-factor apps model and one of these models assumes that your application has no state. You should theoretically take the same application that runs today in your on-prem data center, move it to AWS, and provided there is adequate connectivity, it should just work. Any storage-based solution should be offloaded to either a PCF service, or to a storage solution outside the PCF cluster itself. This may be regarded as an advantage or a disadvantage depending on your application and architecture. For stateless application runtimes such as web servers, it is always a good idea to decouple it from any internal storage facility.Onboarding Kubernetes
Getting started with Kubernetes was not easy. As mentioned above, you can’t just start with a 5-minutes quick start guide, there are just too many things you need to know and too many assumptions about what you already have (docker registry and a git repository are often taken for granted).
Just taking a look at the excellent Kubernetes Basics interactive tutorial shows the level of knowledge required on the platform. For a basic on-boarding, there are 6 steps, each one of them containing quite a few commands and terminologies you need to understand. Trying to follow the tutorial on a local minikube vm instead of the pre-configured online cluster is quite difficult.Cloud Foundry
Getting started with PCF is easy. Your developers already know how to develop their spring boot / nodejs / php / ruby / .NET application. They already know what its artifacts are. They probably already have some jenkins pipeline in place. They just want to run the same thing in a cloud environment.
If we’ll take a look at PCF’s “Getting Started with Pivotal Cloud Foundry”, it’s almost comical how little is required to get something up and running. When you need more complex interaction, it’s all available for you, either in the cf cli, as part of a manifest.yml, or in the web console, but this doesn’t prevent you from getting started quickly.
If you mainly develop server-based applications in java or nodejs, PCF gets you to the cloud simply, quickly and more elegantly.Vision Kubernetes
Kubernetes is truly a great open source platform. Kudos to Google for giving up control and letting the community do its thing. That’s probably the number one reason why Kubernetes has taken off so quickly while other solutions like Docker swarm are falling behind. Other vendors also offer solutions that offer a more PaaS-like experience on top of Kubernetes, such as RedHat OpenShift.
But with such a diverse and thriving eco-system, the path forward can be one of many different directions. It really does feel like a Google product in a way — maybe it will remain supported by Google for years, maybe it will change with barely any backwards compatibility, or maybe they’ll kill it and move to the next big thing (Does anyone remember Google Buzz, Google Wave or Google Reader?). Any AngularJS developer who’s trying to move to Angular 5 can tell you that backwards compatibility is not a top priority.Cloud Foundry
Cloud Foundry is also a thriving open source platform, but it is pretty clear who sets the tone here. It is Pivotal, with additional contributions from IBM. Yes, it’s open source, but the enterprise play here is Pivotal Cloud Foundry, which provides added value like the services marketplace, Ops Manager etc. And on that side, it’s a limited democracy. This is a product that is meant to serve enterprise customers, and the feature set would first and foremost answer those needs.
If Kubernetes is Google, then PCF is Apple.
A little more of a walled garden, more controlled, better design/experience layer, and a commitment for delivering a great product. I feel like the platform is more focused, and focus is critical in my line of work.PKS
The real surprise of the recently announced PCF 2.0 was that all I’ve been talking about throughout this article is now just one part of a larger offering. The application runtime (everything that is referred to as PCF in this article) is now called Pivotal Application Service (PAS). There is also a new serverless solution called Pivotal Function Service (PFS), and lastly — a new Kubernetes runtime called Pivotal Container Service (PKS). This means that Pivotal Cloud Foundry now gives you the best of both worlds: A great application runtime for fast onboarding of cloud-native applications, as well as a great container runtime when you need to develop generic low-level containers.Conclusion
In this article I tried to share my personal experiences of working with both platforms. Although I am a bit biased towards PCF, it is for a good reason — it has served me well. I approached Kubernetes with an open mind, and found it to be a very versatile platform, but also one that requires a steeper learning curve. Maybe I got spoiled by living in the Spring eco-system for too long :). With the latest announcement of PKS, it appears that Pivotal Cloud Foundry is set to offer the best integrated PaaS — one that lets you run cloud native applications as quickly and simply as possible, while also exposing the best generic container runtime when that is needed. I can see this becoming very useful in many scenarios. For example, Apache Kafka is one of the best message brokers available today, but this message broker still doesn’t have a PCF service available, so it has to run externally on virtual machines. Now with PCF 2.0, I can run Apache Kafka in docker containers inside PCF itself.
The main conclusion is that this is definitely not a this or that discussion. Since both the application runtime and the container runtime now live side by side in the same product, the future seems promising for both.

LAS VEGAS -- Don't choose the least expensive of the enterprise cloud storage providers, even if the vendor happens...
to be a big name.
That was the advice from Raj Bala, a Gartner research director focusing on cloud infrastructure, at the Gartner IT Infrastructure, Operations Management & Data Center Conference. Bala cautioned attendees about "horror stories" he has heard from customers that made the cheapest choice, even from "big brand names."
During a post-presentation interview, Bala declined to name any of the enterprise cloud storage providers responsible for the client anecdotes that would "make the hair on your neck stand up." But he cited an example of a customer that used an inexpensive brand-name vendor only to have data unavailable "for days on end."
"And the pricing changed. It went from some really inexpensive price to a much higher price," Bala said. In contrast, he said there is "no way in the world" Amazon Web Services (AWS) would increase prices for its Simple Storage Service (S3). "There would have to be a catastrophic supply chain issue for disk drives -- not even SSDs -- for AWS to have a price increase."
Bala's public recommendation to conference attendees was the following: "Think about the number of years that a vendor has been in this market and their commitment to the market. The last thing you want to do is go with a vendor who says, 'Well, the v1 version of their service didn't work, and we're going to scrap it, and we're going to restart over again.' There are a lot of customers in that boat."
Although Bala's cautionary advice did not note specific enterprise cloud storage providers that abandoned the original versions of their cloud storage services, he did offer frank assessments of each of the major challengers to dominant player AWS.IBM, Oracle rebuild public cloud storage
Bala told attendees that Oracle and IBM are busy rebuilding their public cloud storage. He said Oracle scrapped its open source OpenStack-based platform, because "that just did not work" and "did not get much traction," so the company decided to start over again.
"Oracle did something very smart. They opened a large office in Seattle, and they've hired a bunch of AWS engineers. So, they've got several hundred AWS engineers that are building v2 of Oracle service," Bala said. "After having failed the first time, they're doing some really thoughtful things the second time."
Bala said IBM's public cloud storage, also based on OpenStack, "didn't really go anywhere" and "had lots of problems," leaving the company "trying to rebuild it." He said IBM spent lots of money trying to buy companies, as well as trying to rebuild in-house.
"But IBM's service is a bit of mess," Bala said. "First, they called it SoftLayer. Then, they called it Bluemix. And now, it's called IBM Cloud. And that's all happened in the span of about 2.5 years. I think IBM Cloud is probably what they're going to keep it at. That seems to make the most sense to me. But they could change it next year, as well. Let's see," Bala said.Top-ranked enterprise cloud storage providers
The primary challenger to AWS, No. 2 Microsoft, dipped as a visionary in Gartner's 2017 Magic Quadrant for public cloud storage, because "we're seeing very little in terms of new innovation," Bala said. According to Bala, Microsoft has essentially been "following the AWS roadmap" during the past year.
Bala said Google is putting money into its public cloud storage service, but it's not having success with mainstream enterprise because it lacks a sales force "big enough to go knock on doors." He said Gartner clients ask about Google only 3% of the time, based on his review of the entire set of inquiries on infrastructure as a service. Google's cloud storage customer base tends to include sophisticated enterprises, such as hedge funds, Wall Street banks, and biotechnology and pharmaceutical companies, according to Bala.
"Google is an interesting company. Google can put satellites into space. They can build self-driving cars, but building an enterprise strategy is apparently too much for Google," Bala said.
Alibaba dominates the cloud business in China, but has achieved little success with the data centers it has opened in other locations, according to Bala. He said Alibaba essentially replicates AWS offerings, even to the point of identical names for products.
Bala said Dell EMC's Virtustream cloud storage service, based on EMC hardware, lags in Gartner's innovation ratings, because it relies on software that "hasn't been touched in a good three or four years." Rackspace, once the No. 2 enterprise cloud storage provider, faded due to its inability to keep pace with AWS. Rackspace has pivoted to start focusing on services for AWS, Bala said.Spotty S3 API support
Bala warned conference attendees that compatibility varies greatly among vendors that implement Amazon's S3 API. He said his personal testing showed that some implement the S3 API "dutifully," while other vendors implement only about 40% of the API.
Another area of skepticism for Bala is the increasing number of vendor pitches on multi-cloud strategies. He said the vendors promoting multi-cloud are not the leaders.
"The notion of using multiple clouds is not new, and a multi-cloud architecture is usually problematic. If a customer told me they were doing that, I would throw up big red-flag warnings and say, 'Do not do this unless you absolutely know what you're getting into,'" Bala said.
He said the complexity of an application increases tenfold by spreading it across multiple cloud providers with only marginal benefit. "It doesn't make sense," he said.
Cloud storage price negotiating is another topic on which Bala cautioned clients. He said, because the price of cloud storage falls consistently, it's a mistake to negotiate anything other than a percentage discount. He said some large customers of big providers negotiated a per-gigabyte price only to later find that the market price was less than what they had negotiated.
"If you use a percentage discount, then you're going to get the best price," Bala said. "And most of the vendors -- AWS, for instance -- will start negotiating with you on price if you've got 2 PB of data or more. Microsoft will go a whole lot less. Google will go even further than that."
