The Scala runs on Java platform with these Unique features

Let us start it in layman terms...

Why you need Scala...

The name Scala stands for “scalable language.” The language is so named because it was designed to grow with the demands of its users.

Where Scala can be applied...

You can apply Scala to a wide range of programming tasks, from writing small scripts to
building large systems.

The real use of Scala...
Scala is easy to get into. It runs on the standard Java platform and interoperates seamlessly with all Java libraries. It’s quite a good language for writing scripts that pull together Java components.But it can apply its strengths even more when used for building large systems and frameworks of reusable components. Technically, Scala is a blend of object-oriented and functional programming
concepts in a statically typed language.
The fusion of object-oriented and functional programming shows up in many different aspects of Scala;
It is probably more pervasive than in any other widely used language. The two programming styles have comp…

8 Selected interview Questions for Quick revision

Q1. Explain Elastic Block Storage? What type of performance can you expect? How do you back it up? How do you improve performance? A1. EBS is a virtualized SAN or storage area network. That means it is RAID storage to start with so it’s redundant and fault tolerant. If disks die in that RAID you don’t lose data. Great! It is also virtualized, so you can provision and allocate storage, and attach it to your server with various API calls. No calling the storage expert and asking him or her to run specialized commands from the hardware vendor. Performance on EBS can exhibit variability. That is it can go above the SLA performance level, then drop below it. The SLA provides you with an average disk I/O rate you can expect. This can frustrate some folks especially performance experts who expect reliable and consistent disk throughput on a server. Traditional physically hosted servers behave that way. Virtual AWS instances do not. Backup EBS volumes by using the snapshot facility via API call …
