Senior Java Developer at ScienceSoft

"I’m glad Java remains one of the most popular languages, and all the major clouds provide first-class support for it in their SDKs, which greatly simplifies development and enhances our capacities.

Even serverless architecture can be easily realized in Java today. With AOT (ahead-of-time) compilation for GraalVM and numerous microframeworks, you can efficiently address a long cold start and a big distributive size."
