Postgres
Postgres is the most advanced Open Source SQL database system today. While the MySQL database may be the most popular today, Postgres is certainly the most advanced and powerful. It gives you nearly all of the features of the expensive proprietary database systems (Oracle, SQL Server) at a fraction of the cost and often with greater performance.
We have used Postgres in large scale production environments for ourselves and our clients for decades. We helped our clients reducing TCO significantly by moving their proprietary database systems to Postgres.
Cassandra
Cassandra is a massively scalable open source NoSQL database. Cassandra is perfect for managing large amounts of structured, semi-structured, and unstructured data across multiple data centers and the cloud. Cassandra delivers continuous availability, linear scalability, and operational simplicity across many commodity servers with no single point of failure, along with a powerful dynamic data model designed for maximum flexibility and fast response times.
Cassandra is our first choice of NoSQL data store. We have used Cassandra in production environments and helped clients to migrate data into Cassandra cluster.
DevOps
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market. Our team follows DevOps methodology to work on projects with clients and their teams.
Python
Python is a general-purpose, versatile and popular programming language. It’s great as a first language because it is concise and easy to read, and it is also a good language to have in any programmer’s stack as it can be used for everything from web development to software development and scientific applications. Python is our first choice of language for developing applications.
