Editor's Note: The following is an article written for and published in DZone's 2024 Trend Report, The Modern DevOps Lifecycle: Shifting CI/CD and Application Architectures. Forbes estimates that cloud budgets will break all previous records as businesses will spend over $1 trillion on cloud computing infrastructure in 2024. Since most application releases depend on cloud infrastructure, having good continuous integration and continuous delivery (CI/CD) pipelines and end-to-end observability becomes essential for ensuring highly available systems. By integrating observability tools in CI/CD pipelines, organizations can increase deployment frequency, minimize risks, and build highly available systems. Complementing these practices is site reliability engineering (SRE), a discipline ensuring system reliability, performance, and scalability. View the full article -
In my previous article, I hinted at explaining how Ansible can be used to expose applications running inside a high availability K8s cluster to the outside world. This post will show how this can be achieved using a K8s ingress controller and load balancer. This example uses the same setup as last time around: virtual machines running under the default Windows Hypervisor (Hyper-V). To make room for the addition of a proxy each VM had to give up some RAM. With the exception of the initial master and the Ansible runner, each of the remaining nodes received an allocation of 2000MB. View the full article

Serverless Architectures on AWS helps to build, secure, and manage the serverless architectures to fuel the most demanding web applications and mobile applications. In this article, we’ll cover what is serverless architecture, how serverless architecture works, serverless architecture use cases, and how to build serverless architecture with the help of AWS Services in hands-on labs. This hands-on labs project is designed for individuals working in the roles of cloud architects and cloud developers. It is also suitable for those who are preparing to obtain the AWS Certified Developer Associate certification... View the full article -
Despite being a well-known concept, implementing high availability (HA) remains a challenge for many companies. It’s critical to avoid single points of failure in company infrastructure, but it can be difficult to know where to start. In this Techstrong Learning Experience, we’ll shed light on this issue and explore the topic of HA. Our panel […] View the full article -
When the margin for error is razor thin, it is best to assume that anything that can go wrong will go wrong. AWS customers are increasingly building resilient workloads that continue to operate while tolerating faults in systems. When customers build mission-critical applications on AWS, they have to make sure that every piece in their system is designed in such a way that the system continues to work while things go wrong. AWS customers have applied the principle of design for failure to build scalable mission-critical systems that meet the highest standards of reliability. The best practices established in the AWS Well Architected framework have allowed teams to improve systems continuously while minimizing business disruptions. Let’s look at a few key design principles we have seen customers use to operate workloads that cannot afford downtime... View the full article-

Oracle WebLogic Server is used by enterprises to power production workloads, including Oracle E-Business Suite (EBS) and Oracle Fusion Middleware applications. Customer applications are deployed to WebLogic Server instances (managed servers) and managed using an administration server (admin server) within a logical organization unit, called a domain. Clusters of managed servers provide application availability and horizontal scalability, while the single-instance admin server does not host applications. There are various architectures detailing WebLogic-managed server high availability (HA). In this post, we demonstrate using Availability Zones (AZ) and a floating IP address to achieve a “stretch cluster” (Oracle’s terminology)... View the full article
