Kubernetes for Stateful Applications Running databases, big data and AI/ML workloads in enterprise

Enterprise cloud-native requirements demand a robust platform that can support stateless and stateful workloads along with the necessary performance and SLA guarantees. Robin Hyper-Converged Kubernetes platform is built from the ground up to deploy enterprise applications. With an App-Store model for deploying stateful applications, Robin provides agility to DevOps teams with enterprise-grade performance. Introduction In today’s competitive market, enterprise IT faces an unenviable task of supporting innovation while enabling support for a variety of complex applications. Whether it is new applications with stateless architectures or existing stateful data-intensive applications, IT is expected to be the core part of the innovation team by empowering developers with right abstractions and enabling an agile workflow from developer laptop to production. In order to meet the demands of modern enterprise, IT has embraced cloud-native as the core pillar of their modernization strategy.

Kubernetes is the standard for container orchestration in the cloud-native ecosystem. Kubernetes, developed by Google and now part of Cloud Native Computing Foundation (CNCF), is an open source container orchestration engine used for the deployment, scaling and management of containers. The increase in market demand for Kubernetes is driving the platform as the standard for container orchestration. A vibrant ecosystem has emerged around Kubernetes, increasing the momentum of the project.

In the past two years, more organizations are using Kubernetes in production. According to a recent CNCF survey, 58% of respondents are using Kubernetes in production. This number will increase in the coming years as more enterprises go cloud-native. This trend is further highlighted by the report released by Dice and Indeed.com. Their report claims Kubernetes was the top job searched in 2018 and this trend will grow further in 2019. The advantage of Kubernetes lies in the low operational overhead, easier DevOps and a better abstraction for developers to deploy their applications. Kubernetes supports both on-premises and cloud-based deployments. The support for hybrid/multi-cloud deployments makes Kubernetes attractive for enterprises.

Top 5 Challenges for Oracle-as-a-Service Management

DevOps culture demands faster provisioning and Dev/Test refreshes: Traditional methods of creating IT tickets take weeks to provision new databases or to provide dev/test refreshes of production databases. With release cycles shrinking, developers need much faster turnaround times.

Dynamic scaling to meet sudden demands: If a Database Server runs out of resources, there is no easy way to scale-up the node “on-the-fly” by adding more memory or CPU. Scaling-out Oracle RAC clusters can also take weeks due to process delays.

Massive licensing and hardware 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.

Cloud migration: Migrating Oracle databases and customized applications (e.g. EBS) to cloud is not easy. Lift-and-shift is the easier approach but does not bring the benefits of cloud-native architecture, and refactoring applications to make them cloud-native is expensive and time-consuming.

High availability and auto-failover: Oracle RAC licenses and additional hardware is needed for HA, adding to already high costs.

Containerizing Oracle

Robin Hyper-Converged Kubernetes Platform for Oracle

Still running your databases on underutilized bare metal servers? Looking to consolidate your databases and reduce license costs, but not create an OS sprawl? If the answers are YES, then watch this on-demand webinar to see how Linux container technologies like docker and LXC can help.

We explore how to use containers to consolidate databases without compromising performance, while guaranteeing isolation and no manageability changes. We examine and contrast other prevalent consolidation approaches, along with the roadblocks they present and how containerization helps you overcome those problems.

We show you how to:

  • Configure an Oracle database on LXC
  • Apply IO resource management on your Oracle database running in a container
  • Simplify database lifecycle management tasks with single click clone, time travel

Core Elements to Running an Oracle database using Docker

The core elements are:

  • Storage
  • QoS
  • Data Sharing
  • Availability

Storage: How do I configure storage for the Oracle database running in a Docker container?

In my opinion, this is probably the most important question when considering running an Oracle database using Docker. Running a database in a container actually provides the unique opportunity to decouple the compute from the storage.

QoS: How do I consolidate without worrying about noisy neighbors?

One of the key virtues of virtualization is the ability to share the system resources across many applications. While traditional VM based virtualization has seen some adoption in Dev and Test systems, the inability to ensure predictable performance has forced enterprises to use bare metal servers for production databases.

Data Sharing: How do I share data across environments?

I am often asked this or a slight variation of this question – “Will I be able to share data across Dev and Test environments if I run my application database using Docker?” The answer is Yes, if you plan and configure your storage correctly.

Availability: Can I ensure application availability across machine failures?

As I mentioned above, handling failover or relocation (read as managed failover) of the database instance by moving the container from one host to another is a very important requirement for running databases in general. Today a similar capability exists in RAC One but it requires a dedicated and often an idle machine for instance failover. Not to mention the extra license cost.
