AWS Certifications - Types of AWS Certifications

AWS certifications are aligned to two broad streams – Solutions Architect and DevOps Engineer. The Solutions Architect stream is well defined; you should first bag the Solutions Architect – Associate certification followed by the Solutions Architect – Professional certification. But if you choose to certify yourself as an AWS DevOps Engineer, you have to either clear the Developer – Associate certification or the System Operations (SysOps) Administrator – Associate certifications. Of course, you should choose based on your current job or the stream of specialization you aspire for.

Alternatively, AWS allows you to containerize its suite of certifications into three blocks – Solutions Architect,Developer and SysOps. While Solutions Architect is an independent stream in itself, a Developer and/or SysOps Associate certification can lead you to a DevOps Engineer certification.

Apache Cassandra - Features of Apache Cassandra - Learn Apache Cassandra

Apache Cassandra:

What is Cassandra?

The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance.

Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.

Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages.

Features of Cassandra

Cassandra has become so popular because of its outstanding technical features. Given below are some of the features of Cassandra:

Elastic scalability - Cassandra is highly scalable; it allows to add more hardware to accommodate more customers and more data as per requirement.

Always on architecture - Cassandra has no single point of failure and it is continuously available for business-critical applications that cannot afford a failure.

Fast linear-scale performance - Cassandra is linearly scalable, i.e., it increases your throughput as you increase the number of nodes in the cluster. Therefore it maintains a quick response time.

Flexible data storage - Cassandra accommodates all possible data formats including: structured, semi-structured, and unstructured. It can dynamically accommodate changes to your data structures according to your need.

Easy data distribution - Cassandra provides the flexibility to distribute data where you need by replicating data across multiple data centers.

Transaction support - Cassandra supports properties like Atomicity, Consistency, Isolation, and Durability (ACID).

Fast writes - Cassandra was designed to run on cheap commodity hardware. It performs blazingly fast writes and can store hundreds of terabytes of data, without sacrificing the read efficiency.
