Connecting MongoDB to Ruby with Self-Signed Certificates for SSL

Scalegrid

In this blog, we’ll show you how to connect to a MongoDB server configured with self-signed certificates for SSL using both the Ruby MongoDB driver and the popular Object-Document-Mapper (ODM) mongoid. The connection options available for the driver are documented here , and the options we will need are: :ssl. We will use a yaml file to provide configuration to mongoid, and the details of such a config file are documented here. The user's database roles.

Document Model Support in DynamoDB: Flexibility, Availability, Performance, and Scale.Together at last

All Things Distributed

We are introducing native support for document model like JSON into DynamoDB, the ability to add / remove global secondary indexes, adding more flexible scaling options, and increasing the item size limit to 400KB. Now that we have added support for document object model while delivering consistent fast performance, I think DynamoDB is the logical first choice for any application. These databases trade off complex querying capabilities and consistency for scale and availability.

NoSQL Data Modeling Techniques

Highly Scalable

NoSQL databases are often compared by various non-functional criteria, such as scalability, performance, and consistency. At the same time, NoSQL data modeling is not so well studied and lacks the systematic theory found in relational databases. Document Databases: MongoDB, CouchDB.

How to Monitor MySQL Deployments with Prometheus & Grafana at ScaleGrid

Scalegrid

Monitoring your MySQL database performance in real-time helps you immediately identify problems and other factors that could be causing issues now or in the future. It’s also a good way to determine which components of the database can be enhanced or optimized to increase your efficiency and performance. This is usually done through monitoring software and tools either built-in to the database management software or installed from third-party providers.

A one size fits all database doesn't fit anyone

All Things Distributed

A common question that I get is why do we offer so many database products? To do this, they need to be able to use multiple databases and data models within the same application. Seldom can one database fit the needs of multiple distinct use cases. The days of the one-size-fits-all monolithic database are behind us, and developers are now building highly distributed applications using a multitude of purpose-built databases. Purpose-built databases.
