Microservices are frequently referred to as a variant or derivative of service-oriented architecture (SOA), if not essentially the same thing. While there are similarities and both are designed around the concept of services, that’s where the similarities end. Each was created around a different set of principles and intended to address different problems. Microservices architecture […]
Microservices: The Advantages of SOA Without Its Drawbacks
Service Oriented Architecture (SOA) was the great hope of organizations decades ago when they sought to advance legacy system integration, reduce and bypass layers, and rapidly access the system of record. At the time, the existing solution was point-to-point integration, creating a brittle “spaghetti” middle layer that was hard to manage. This was replaced by […]
Containers, Service Mesh and API Gateways: It Starts at the Edge
Anyone embracing container technology such as Docker or Kubernetes has no doubt heard about the associated next big thing: service mesh, which promises to homogenize internal network communication between microservices and provide cross-cutting nonfunctional concerns such as observability and fault-tolerance. However, the underlying proxy technology that powers a service mesh also can provide a lot […]
The Executive’s Guide to Microservices: Chapter 1
Meet Steve. Steve is responsible for a mission-critical application for a very large enterprise. He has a problem: It takes Steve and his team a very long time to make changes to this application and release it to production. Steve has been talking to vendors, consultants and peers about agile software development techniques and DevOps, […]
SOA vs Microservices
Some say microservices architecture is proof that SOA is still alive. I contend that microservices architecture replaces SOA due to deficiencies in how SOA has been implemented as well as the original intent. In the mid-1990s there was a surge of investment for implementing enterprise applications to replace the aging homegrown legacy applications. These new […]
DevOps Debates: Monoliths or Microservices
From the time software came into existence, application software has been booming to leverage the benefit of the computing paradigm. During this cycle, it has transformed decades of design and architectural thinking, and has crossed all aspects of application development and management needs, be it configurability, reusability, maintainability, scalability or security (a good list is of […]
What’s hot with DevOps
DevOps as a movement to transform people, technology, processes for higher business value is here to stay. It’s disrupting organizational processes replacing the old with the new. Command and control IT, a historical approach to regulating tech top-down, is trending toward decentralization thanks to DevOps. Software source control is another such case. We saw Git take on the source control […]
3 golden rules of microservices deployments
As a developer, you value the principles of SOA. You aspire to build applications as a set of consumable services via endpoints. Remember how Amazon used SOA to build the AWS platform and how Google is emulating AWS? However, not all is hunky-dory in the SOA world. Developing is one thing but running, managing, and […]
