Arnon Rotem-Gal-Oz believes that something is either a monolith or a microservice is nonsense. He also believes that more and more implementations which claim to be microservices will not live up to all of the principles. However, he does not discount the need for semi-independently deployable software components and discusses an approach he has found useful, which he call Aspects.
In a recent blog post, Amazon announced changes to its NoSQL database service, DynamoDB, that includes support for Time to Live (TTL) on data stored in the service. Deleting data, based upon time-based thresholds, provides opportunities for organizations to reduce storage costs for data that decreases in value over time.
Deliveroo has grown dramatically the last years, both in terms of business and IT, and is facing a lot of technical challenges with its large monolithic application. The solution is to go distributed, but without microservices, Greg Beech noted in his presentation at the recent QCon London conference, describing their move from a monolith into a distributed system.
The world is concurrent with everything around us asynchronous and event oriented. Concurrency and the cloud are things every developer will have to deal with in the future, Joe Duffy claimed in his keynote at the recent QCon London conference. At the heart of this is communication, which is essential both for concurrent and distributed systems.
Apache Ranger, a security management framework for Apache Hadoop ecosystem, graduated to top level.
