Monitor Hazelcast with Datadog

Hazelcast is a distributed, in-memory computing platform for processing large data sets with extremely low latency. Its in-memory data grid (IMDG) sits entirely in random access memory, which provides significantly faster access to data than disk-based databases. And with high availability and scalability, Hazelcast IMDG is ideal for use cases like fraud detection, payment processing, and IoT applications.


22,900 MongoDB Databases Held to Ransom by Hacker Threatening to Report Firms for GDPR Violations

Hackers are once again finding unsecured MongoDB databases carelessly left exposed on the internet, wiping their contents, and leaving a ransom note demanding a cryptocurrency payment for the data’s safe return. As ZDNet reports, ransom notes have been left on almost 23,000 MongoDB databases that were let unprotected on the public internet without a password. Unsecured MongoDB databases being attacked by hackers is nothing new, of course.

Can Lambda and RDS Play Nicely Together?

AWS Lambda, the most popular and widely used serverless cloud computing service, lets developers run code in the cloud and frees them from dealing with server provisioning or management. Amazon Relational Database Service (RDS) is a more traditional, server-based service that provides you with SQL databases. It will do some heavy lifting, but you’ll still need to do proper server provisioning and management. Can AWS Lambda and RDS work together seamlessly?


Best Practices for Database Performance Monitoring

Like application monitoring, database performance monitoring is a critical discipline. If there isn’t a code issue, there’s a good chance you have a database issue. Key metrics such as CPU and memory usage can give you important insights into your database’s performance. In addition, by monitoring slow queries, and inordinate number of database requests, you can combine this knowledge to optimize both.


SQL Server, Part 4: Understanding built-in SQL Server principals

In the previous blog in this series, we discussed the principle of least privilege, and the importance of assigning bare minimum privileges to users and systems at database or server levels. However, there are certain built-in principals in your database that possess all permissions in SQL Server. If an attacker managed to get hold of one of these principals, the database could be easily exploited and damaged.
