Kubernetes Cluster Automated Upgrade in Jelastic PaaS

Flexibility, accelerated development and delivery, improved scalability and high availability are the main reasons companies are adopting Kubernetes (K8s) technology. But managing and keeping the system up to date can be so complex for organizations that they need to hire a separate department just to handle everything properly.

With Jelastic’s Kubernetes automation you can improve DevOps productivity and focus on your business aims rather than fighting infrastructure complexity. In this article, we will cover how to streamline the Kubernetes cluster lifecycle via delivering upgrades automatically.

The Right-Sizing Problem in Cloud Computing: Reasons and Solution

Today, businesses of every shape and size are reliant on the Internet — even the smallest ones have at least a website for representation and advertising, while some are run entirely online. However, maintaining a company’s own servers is a costly and tedious procedure, which creates the need in cloud computing services.

Cloud computing stands for the delivery of computing services on demand (storage and processing power) over the Internet.

Hybrid Cloud Implementation for Enterprises

As part of the digital transformation and technology modernization, many large enterprises are looking at embarking on a transformation roadmap to enable a hybrid cloud framework to address the following:

  • Modernize legacy applications and coexist with cloud-native applications.
  • Automate technology operations to enable agility and speed of delivery.
  • Optimize TCO to address increase workloads due to business demand.
  • Improve service quality.

This article focuses on key enablers that will be required for building a hybrid-cloud architecture and operating model to support the enterprise goals and transformation strategy, especially with the accelerated and increased adoption of digital services in a post COVID world.

50+ Useful Kubernetes Tools List – Part 2

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

Migrating to Microservices — A Roadmap

Migrating to microservices often sounds like a huge and complex task. While there are complexities in the process, it's actually easier than you might think. This blog creates a basic roadmap for migrating to microservices using a standard J2EE application from a monolithic architecture to a microservice architecture. We will start by first containerizing our Java application and end with auto-deploying to a Kubernetes microservice environment.

Step 1: Containerize Your Java Application and Runtime

Start your migration journey by first containerizing your Java Application (.jar, .war or .ear). This will involve building a container that includes the Java runtime as well as your application. When you do this, remember the following:

Working With AWS And Kubernetes Together

Many developers now package the various services that comprise their applications into separate containers. These containers can then be deployed across clusters of machines, whether virtual or physical. This is a neat and attractive way of approaching software development that also necessitates another innovation—container orchestration. Leading container management tool Kubernetes automates the creation, configuration, scaling, networking, and other facets of container-based applications.

As a way to containerize applications in a cloud environment, Kubernetes offers a lot of flexibility. You can structure your web application into pods, contain processes or functions separately, and create complex communications between worker nodes in different pods. The way Kubernetes is designed to be flexible resembles that of Amazon Web Services and the tools it offers. One such tool in particular, Amazon EKS, is a certified Kubernetes conformant which means you can use existing tooling and plugins from partners and the Kubernetes community on the AWS platform. The service allows you to deploy Kubernetes instances without managing them manually.

Watch Out for These Five Kubernetes Storage Potholes

Kubernetes and containers have been revelatory for application development, but they’re not the complete solutions enterprises might like them to be. Yes, both address organizations’ long-held desires for agility, efficiency, and accelerated application development. However, there remain some missing elements that may hold back Kubernetes’ explosive adoption rate for mission-critical workloads in the modern enterprise.

All of these elements can be traced back to the fact that neither Kubernetes nor containers feature native storage. Although historically seen as an afterthought by developers, storage remains an essential component for enterprise applications, especially in the age of containers.
