"Microservices based architectures are not new but are suddenly in the spotlight due to their powerful and sophisticated practices enabling streamlined application development and deployment. However, transitioning from a monolithic approach to a microservices-based architecture requires not only technical expertise, but organizational buy-in as well. In a recent ActiveState webinar, John Wetherill and Phil Whelan discussed a number of tips and tricks to help companies transition to and get the most out a microservices-based approach."

"Tony Tam shares tips for modeling data with MongoDB for a fast and scalable system based on his experience migrating billions of records from MySQL to MongoDB."

"In incoming Play2.1 version, a huge re-thinking has been done about JSON API provided by Play2.0.x which provides some great features but is clearly just the tip of the iceberg… Here is a first presentation of those evolutions aimed at unleashing your JSON usage in Play2 and revealing new forms of manipulation of web dataflows from/to external data systems. A usecase of this is manipulating DB structures directly using Json without any class models for document oriented structures such as MongoDB"

"A typical Java EE application consists of an application server, such as WildFly, and a database, such as MySQL. In addition, you might have a separate front-end tier, say Apache, for load balancing a number of application server. A caching layer, such as Infinispan, may be used to improve overall application performance. Messaging system, such as ActiveMQ, may be used for processing queues. Both the caching and messaging components could be setup as a cluster for further scalability. This Tech Tip will show some simple Docker recipes to configure your containers that use application server and database. Subsequent blog will cover more advanced recipes that will include front-end, caching, messaging, and clustering. "

The ss command is used to show socket statistics. It can display stats for PACKET sockets, TCP sockets, UDP sockets, DCCP sockets, RAW sockets, Unix domain sockets, and much more. It allows showing information similar to netstat command. It can display more TCP and state information than other tools. It is a new, incredibly useful and faster (as compare to netstat) tool for tracking TCP connections and sockets. SS can provide information about: All TCP sockets. All UDP sockets. All established ssh / ftp / http / https connections. All local processes connected to X server. Filtering by state (such as connected, synchronized, SYN-RECV, SYN-SENT,TIME-WAIT), addresses and ports. All the tcp sockets in state FIN-WAIT-1 and much more. Most Linux distributions are shipped with ss and many monitoring tools. Being familiar with this tool helps enhance your understand of what's going on in the system sockets and helps you find the possible causes of a performance problem.
