CosmosDB is Microsoft's multi-model database that can be accessed using multiple APIs and provides options for consistency and geographic distribution of data across regions. It supports document, key-value, graph and table-based data models and can be accessed via SQL, MongoDB, Cassandra, Azure table and Gremlin APIs. Data can be distributed globally across regions while maintaining various levels of consistency including strong, bounded staleness, session, or eventual.

MongoDB
MongoDBRony Gregory MongoDB is a document database that stores data in BSON format, which is similar to JSON. It is a non-relational, schema-free database that scales easily and supports massive amounts of data and high availability. MongoDB can replace traditional relational databases for certain applications, as it offers dynamic schemas, horizontal scaling, and high performance. Key features include indexing, replication, MapReduce and rich querying of embedded documents.

When constructing a data model for your MongoDB collection for CMS, there are various options you can choose from, each of which has its strengths and weaknesses. The three basic patterns are:
1.Store each comment in its own document.
2.Embed all comments in the “parent” document.
3.A hybrid design, stores comments separately from the “parent,” but aggregates comments into a small number of documents, where each contains many comments.

The presentation contrasts traditional relational database implementations with NoSQL data stores, identifying five categories of NoSQL data models: document, key-value, graph, and column family. It provides examples of databases that fall under each category. The presentation concludes with a comparison of real-world scenarios and which data storage solutions might be best suited to each scenario.

MongoDB Replication fundamentals - Desert Code Camp - October 2014
MongoDB Replication fundamentals - Desert Code Camp - October 2014clairvoyantllc MongoDB uses replication to provide high availability and scalability. The primary node accepts all write operations and logs the changes to the oplog (operation log), which secondary nodes replicate from to stay in sync. The oplog contains entries for all insert, update, and delete operations with metadata like the timestamp and operation. It acts like a rolling queue to support replication as older entries are overwritten. Replication allows increased read capacity and redundancy for disaster recovery.

It provides an overview of AppFabric, why distributed caching is useful, how to configure AppFabric clients and servers, and how to manage data in an AppFabric cache, including concurrency and high availability. While version 1 has some limitations, it is suitable as a session state provider, and the author expects version 2 to improve the product.

Velocity - NxtGen Oxford
Velocity - NxtGen OxfordPhil Pursglove Velocity is a distributed cache that allows sharing of cached data across multiple servers. In version 1, it is best suited for session state caching due to limitations in handling dependencies between cached objects. Future versions will expand its capabilities to support full output caching and read-write operations. Currently, Velocity provides a basic set of cache operations and management functionality through its client and server configuration.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

Designing Low-Latency Systems with Rust and ScyllaDB: An Architectural Deep DiveScyllaDB Want to learn practical tips for designing systems that can scale efficiently without compromising speed?
Join us for a workshop where we’ll address these challenges head-on and explore how to architect low-latency systems using Rust. During this free interactive workshop oriented for developers, engineers, and architects, we’ll cover how Rust’s unique language features and the Tokio async runtime enable high-performance application development.
As you explore key principles of designing low-latency systems with Rust, you will learn how to:
- Create and compile a real-world app with Rust
- Connect the application to ScyllaDB (NoSQL data store)
- Negotiate tradeoffs related to data modeling and querying
- Manage and monitor the database for consistently low latencies
