Digital Transformation Demands Fast-paced Innovation Digital Transformation requires IT services to be delivered in a fast, agile and streamlined manner across the entire organization. Enterprises in the Financial Services industry constantly need to innovate to attract and retain customers demanding a rich digital and mobile experience. It is also critical to analyze security threats across diverse systems and applications in real-time and at the same time meet all the compliance requirements as well as achieve continous availability for critical applications.

The industry is looking at containerization and kubernetes to achieve IT agility, however, there are many challenges that significantly impact the ability of technology leaders to innovate: Infrastructure silos – Owing to years of organic growth, the application infrastructure landscape is very diverse.

Managing legacy applications and modern cloud-native applications at the same time can be challenging. Traditional methods take weeks to provision legacy applications or to provide dev/test refreshes. With release cycles shrinking due to the DevOps culture and modern architecture, developers need much faster turnaround times for their application pipeline that often include legacy applications, as many modern applications depend on legacy applications.

High licensing and Infrastructure costs – Creating dedicated clusters for individual “tenants” (teams, workloads, applications, etc.) is required due to challenges with performance isolation. Each cluster is deployed for peak capacity, leading to significant licensing and hardware costs.

Infrastructure lock-in – Migrating customized applications to the cloud is not easy. Locked into infrastructure choice limits your ability to scale and experiment with new ideas.

How to Bring Cloud-Native Computing to the Enterprise White Paper

As the complexity of modern IT continues to explode with no limits in sight, organizations are increasingly leveraging cloud-native computing to bring the best practices of the cloud to their entire IT organization.

An essential enabling technology for this next-generation approach to architecting IT infrastructure is the use of containers in conjunction with the Kubernetes container orchestration platform.

Containers bring dramatically improved flexibility to the applications that enterprises put in front of customers but lack a sufficiently comprehensive way to maintain persistent information over time because containers are inherently stateless.

Managing state information in such a stateless environment, therefore, is one of the primary challenges facing enterprise deployments of Kubernetes. Both, ROBIN platform and ROBIN storage, solve the challenges by enabling stateful workloads that follow cloud-native principles.

What is ‘Cloud-Native’?

For all its transformative power and business value, cloud computing has unquestionably been a lightning rod for hype.

This buzzwordiness continues with little hope of abating. Today, it swirls around such terms as cloud-native. In common parlance, cloud-native refers to software that developers have built-in – and for – the cloud.

This concept is strikingly important to how enterprises take advantage of the cloud – and even more so, extend the value of the cloud to their IT organizations at large.

From the enterprise perspective, this definition of cloud-native might apply to some of the new software they’re building, but the cloud-native world would forever be separated from the on-premises context for enterprise IT that has been with us for generations.

Fortunately, this definition is shifting. Today, ‘cloud-native’ is more than ‘cloud only.’ It means bringing cloud-centric best practices to software and IT generally, whether that be in the cloud or on-premises – or both.

Oracle RAC Database as a Service – Provision with ROBIN Platform

See how easy it is for anybody to stand up an entirely new Oracle RAC environment including the grid infrastructure installation the ASM configuration and finally create the RAC database tool.

Log into the Robin Hyperconverged Kubernetes Platform console. Go straight to the application bundle screen. In this case, we just have a couple of simple bundles, one of which is our Oracle RAC bundle. So we’ll just simply click on that to provision Oracle RAC. On-click, we are immediately presented with the provisioning workflow associated with this application.

We will name our application. We’ll just call this Oracle RAC demo. Now we’ve got a couple of network interfaces we need to consider because for Oracle RAC both the public and private IP address ranges are available here. This is where we specify the public address because this is how the application will receive connection requests we’ve got the ability to specify the size of the cluster – both in terms of the number of nodes and the amount of compute and memory capacity.

This gives us the ability to shape the way in which the database will be laid out. In this case, we are going to change the default from flash to spinning disk because we, in this case, don’t have enough flash memory available for this particular deployment. We will then move down here to specify our private interconnect IP address and specify our single client address name for RAC. We’ll scroll on down to find a number of other environment variables which may be passed through robin for this deployment.

We’ve got the ability to define how we will declare ASM disk group redundancy – various credentials and then we have our placement rules where we can control how these resources will be deployed on the physical robin cluster. In this case, we need to be able to allow for multiple RAC instances on the same physical node in the cluster because we only have two nodes in our demo environment.

Simply click on provision application from that screen. This will kick off the deployment of our RAC environment. The provisioning process goes through a number of different phases beginning with the deployment of the V nodes or the actual virtual nodes or pods in the cluster running a variety of scripts to complete the configuration of the RAC environment itself from an Oracle perspective through the UI. After this, it is really just in a matter of minutes as we have our entirely fresh new RAC environment up and running.

Scale Out Oracle RAC Database as a Service with ROBIN Platform

Oracle RAC Database as a Service – How to Scale

See how easy it is for anybody to stand up an entirely new Oracle RAC environment including the grid infrastructure installation the ASM configuration and finally create the RAC database tool.

You have seen how easy it is to deploy a fresh new Oracle RAC database environment. But what if we want to know how our workload might respond when adding a third node to the cluster? In other words, test the scalability of that particular workload when adding a third node.

So it’s really easy. We just click on “Scale Out” for the application and here we can define the number of nodes by which we want to extend this cluster. This is done simply by sliding across this bar but for this demonstration purpose, we need to add a single node. We can also explicitly
call out a hostname for the new node. We can go back and tweak some of the environment variables as input for this new operation but for this demo, we really don’t need to make any of these changes.

So let’s just close these out and just simply click on the “Scale Out” button to begin the process for extending our RAC cluster. Behind the scenes, Robin is making all the necessary calls to Oracle to affect the extension of the cluster – in very much the same way as you might through conventional means for any other installation ensuring that from an Oracle perspective things are all agreeable with the configuration. You can see the success of the operation in this window. We’ll close this window and now we are back on our application screen with the newly refreshed view to find that our third node has been added.

We can see the new IP addresses – the physical host on which the new container has been deployed. Let’s just jump back into the new container – rather do a similar verification to see that we have actually successfully reshaped RAC database environment with three nodes from two nodes. We now log into Oracle set our environment through SRB CTL. Let’s just do a status again of our Robin database so we can see that we’ve got our Robin three instance now, which has been added and it’s now running on our new V node.

In the new container in the Robin cluster, we can see the new vip is added and is up and running. The resources have been successfully configured across the new node and if we go back into SQL plus and log back into the database itself and do once again a query of gv$instance, we can see that we had the databases up and fully available across all three instances of the cluster. Okay, so we exit out of that. We’re back to the UI and so now what if we want to scale back in? So we need to shrink that cluster – testing is completed – so we need to shrink that cluster back to two nodes –

Watch the demo to understand how to scale back.

Clone Oracle RAC Database as a Service with ROBIN Platform

Clone Oracle RAC Database as a Service with ROBIN Platform

Clone Oracle RAC Database as a Service with Robin Platform

We have a database application that is up and running. Now let’s take a look at how easy it is to take snapshots of that application and then subsequently perform cloning operations.

Create Snapshot

Creating a snapshot is quite easy with Robin. We have the option to provide a name for the snapshot or just use the default – which is what we’ll do here. We can look at some of the operations behind the scenes that are going to occur with respect to freezing IO and quiescing the application to maintain consistency. We will then see the newly created snapshot.

From here we have the option for restoring back to that point in time or in this case we were going to perform a thin clone operation based on that snapshot. Here we want to name the clone. It’s essentially an entirely new application stack that will be stood up as part of this operation. So we need to give it a name just as we would give the original application when it was provisioned.

Therefore, we also need to specify both the public and the private IP addresses, because again, this is a RAC database application. We could tweak the capacity for this app and we’ll just leave that the same specify the private IP address and just simply launch the operation by clicking on the clone. This takes a few minutes.

We can again take a look at some of the operations that are occurring behind the scenes with respect to deploying the application. It’s relatively quick and at this point, we can close out this window.

View Oracle RAC Clone and the original application

Now we will be presented with the new application screen as it relates to this new clone cloned app with all the related information in terms of the new nodes that have been provisioned – IP addresses etc. So then if we go back and just click on the general application screen then we can get a summary. you can see the original application and the newly cloned deployment and the snapshot on which it was based.

Abstract

This report describes how ROBIN Storage delivers bare-metal performance and enterprise data management for stateful containerized applications on Kubernetes.

The Challenges

As organizations continue to pursue digital transformation initiatives, many have adopted container technologies to streamline application needs, get applications to market faster, and make them more portable. At the same time, Kubernetes has become the orchestrator of choice for deploying, managing, and scaling containers. While development remains a key container target, more organizations are deploying containers in production applications. When ESG asked IT managers about their production container usage in 2018, 56% reported having already deployed applications in production, 24% reported testing with a plan to deploy within a year, and another 16% reported that they expected to start testing production containers in the next year.1

Why the increased interest? Container technologies abstract applications from hardware by virtualizing the operating system, which is a lightweight design that makes them efficient, reliable, scalable, and portable. Containers enable development autonomy and agility, as developers can do more on their own without IT provisioning or management. The infrastructure and staffing efficiency of containers result in lower costs and streamlined processes.

Stateless containers have no need to keep data persistent once the processes they are executing have finished. A key challenge for running enterprise-class, container-based production applications is that they are most often stateful: that is, the applications maintain data from each compute session, even when the container terminates. As a result, running applications such as databases, artificial intelligence/machine learning (AI/ML), or custom-built applications on Kubernetes requires external storage that outlasts the container. When running mission-critical processes, these applications need swift storage provisioning, predictable performance, full data protection and security, easy data sharing, and the flexibility to leverage hybrid/multi-cloud deployments.

There are numerous external storage solutions that support containers through Container Storage Interface (CSI)-compliant APIs to manage interactions between container orchestrators such as Kubernetes and storage arrays. However, these solutions do not provide the performance and data management capabilities that enterprise production applications demand. They provide storage at the volume level but cannot deliver application-level data services.

The Solution: ROBIN Storage

ROBIN Storage is a CSI-compliant, container-native, software-defined block storage solution that offers enterprise-class performance and data management capabilities for Kubernetes-orchestrated containers. It provides resilient storage (supporting HDD, SSD, and NVMe) with bare-metal performance, and has built-in data rebalancing, disk and I/O error-detection, volume rebuilds, and hotspot detection.

Application Aware Storage For GKE and OpenShift

Application Aware Storage For GKE and OpenShift

Summary

As more and more enterprises move to Kubernetes for their cloud-native needs, they are
looking for high-performance storage options for their stateful and data-intensive
workloads. Beyond a seamless workflow to provision storage, they are also looking for
complete data lifecycle management features as a part of their storage platform. ROBIN
Storage is a perfect candidate for this need. With their application awareness, high
performance and scale, ROBIN Storage is well suited to meet enterprise cloud-native
storage needs. Robin has already partnered with Google Cloud and Red Hat OpenShift to
deliver their customers with high-performance storage. They are also well positioned to
work with any Kubernetes platform.

Introduction

As Kubernetes gains increasing enterprise adoption, the need for supporting stateful
applications becomes a critical need. Kubernetes community is working on supporting
stateful applications on the platform but the enterprise needs are different from running
basic stateful apps. Many enterprises are forced to migrate their mission-critical legacy
applications to container environments to ensure that both their legacy and modern
applications are hosted on Kubernetes clusters. This brings into focus the need for a
comprehensive storage platform that meets the critical enterprise needs such as

  • Ease of use without developers having to manage additional operational overhead.
    Provisioning and managing storage should be integrated into the developer workflow
  • Bare-metal like performance
  • High availability
  • Comprehensive data management capabilities

While most Kubernetes platforms meet the compute and networking needs of enterprise
workloads, very few platforms are capable of meeting the performance and data
management needs of the enterprises.
According to Rishidot Research’s analysis of market trends and our discussions with
enterprise stakeholders, more than half of the enterprises are expected to deploy
container based workloads by 2020. Almost three-thirds of our research participants are planning to use containerized workloads also said they are planning to deploy Stateful
workloads on Kubernetes. There is a clear market need for storage solutions that work
seamlessly with Kubernetes. As more and more big data and machine learning workloads
move to Kubernetes, high performance becomes the core requirement for Kubernetes
storage. Robin’s platform features meet these requirements and, recently, they
announced partnerships with both Google Cloud and Red Hat OpenShift. In this short
whitepaper, we will talk about the state of stateful applications in Kubernetes and how
ROBIN Storage meets the enterprise needs of Google Cloud and OpenShift customers.

The state of stateful applications in Kubernetes

Running stateful applications in Kubernetes is challenging even with the progress made by
the Kubernetes community on StatefulSets and support for many Persistent Volumes.
According to the CNCF survey, the critical challenges for running containers in production
are security, complexity, storage, and networking. The enterprise needs are much
different from modern applications as they have legacy and data-intensive
applications in the mix. Even with StatefulSets, trying to bring up clusters, handling node
failures, managing routing, ensuring HA, etc. for databases or big data workloads requires
a great deal of coding and operational overhead. Using storage volumes with Kubernetes
includes managing volume level primitives that adds operational overhead. As developers
push for ease of access to resources, managing multiple configuration settings to deploy
stateful applications is a non-starter for developers in the modern enterprise.

Critical Enterprise Needs

– Application Aware Storage
– Ease of use without developers having to manage additional operational overhead.
Provisioning and managing storage should be integrated into developer workflow
– Bare-metal like performance
– High availability
– Comprehensive data management capabilities on Kubernetes
