Adopting microservices as part of your technology stack Businesses of all sizes should consider using microservices rather than custom code when available. In fact, microservices have leveled the technology playing field to a large extent. Small businesses were once at a severe disadvantage to the 'big guys' that could afford large data centers and the staff to run them. Now, organizations of 1 or 100,000 people can access the same Amazon and Google APIs and leverage the assets of these tech giants. For smaller businesses, microservices can serve as a 'force multiplier' in that they allow you to quickly build complex applications by using services that someone else builds and maintains. Thousands of startups have even combined existing services creatively, or built services to fill a specific niche, and turned them into a business. … [Read more...] about Microservices 101: A guide to microservice architecture

This also can make maintaining code more straightforward. For monolithic applications, updating code can present a major burden because of the difficulty inherent in covering all dependencies. As Ophir Gross has noted, "Spaghetti code is full of checks to see what interface version is being used and to make sure that the right code is executed. It's often disorganized and usually results in higher maintenance efforts as changes in code affect functionality in areas that are challenging to predict during development stages." … [Read more...] about How to avoid turning microservices into distributed spaghetti code
Transitioning to microservicesFor starters, duplicate Amazon's move and mandate that all new software projects be delivered through microservices. If that's too challenging, it may be easier to start more simply. Probably the best place to do that is when acquiring new software or platforms. This is easy when buying cloud software as a service, as most providers deliver a suite of prebuilt microservices to interact with the data and business logic. … [Read more...] about How to plan a microservices implementation
That concept is antithetical to microservice architecture. According to IBM, a "microservices component that is reused at runtime throughout an application results in dependencies that reduce agility and resilience." In the microservice world, it would even be preferable to duplicate code and accept data duplication to further decouple microservice components. The goal is complete independence of each part of an app, not interoperability between different ones. … [Read more...] about SOA versus microservices: How are they different?
No matter how big your organization, you're never going to have enough security resources to penetration test every application, or look at every line of code. Again, one of the cardinal virtues of microservices is that they accelerate change within and between applications. Going back to those developer surveys, companies have historically tried to build spreadsheets with a score attached to each application or service, but this has the problems mentioned above, as well as the difficulty (read: impossibility) of keeping it up-to-date. If you have hundreds (or even dozens) of applications that change all the time, it's unwise to rely on people volunteering information in a timely or accurate fashion. … [Read more...] about Best practices for securing microservices
