dynamodb vs other nosql

Instead of the relational model, NoSQL databases (like DynamoDB) use alternate models for data management, such as key-value pairs or document storage. On the upside, you get tight integration between DynamoDB and other AWS tools, but at the price of zero portability. This is common across all NoSQL databases. Mongo B is developed by MongoDB Inc, a US based software company. The great news is that companies and teams can buy managed Cassandra clusters also. MongoDB also has a paid offering (priced on application) – MongoDB Enterprise Advanced, which includes additional features such as: MongoDB can be run on customer managed servers, or with MongoDB Atlas on AWS, Azure and GCP. SQL is the standard for storing and retrieving data. In this article, we will compare two database systems and help with pointers that one should keep in mind while deciding on which database to use for your applications. Overall, Cassandra can handle large volumes of data across distributed and decentralised servers. I think one of the key differences between DynamoDB and other NoSQL offerings is the provisioned throughput - you pay for a specific throughput level on a table and provided you keep your data well-partitioned you can always expect that throughput to be met. So if you need a NoSQL database to be compatible with a specific language then it may be you are forced to choose one option over the other. Autoscaling of database tables, throughput and storage for performance and capacity as database traffic grows and shrinks. As it is managed by Amazon, users do not have to worry about operations such as hardware provisioning, configuration and scaling. This pricing model works best for predictable or consistent application traffic, and may work out more cost effective for users who are able to accurately forecast demand. But DynamoDB is only available in AWS and nowhere else. ... it uses it’s own products to power their other products. Users of AWS DynamoDB simply need to follow standard programming best practise, the rest is taken care of by AWS under their role in the ‘Shared Responsibility Model’ for security. Common use cases vary by industry, but include: AWS have 2 pricing models for DynamoDB – users are charged for reading, writing and storing data in Dynamo DB tables. Keep in mind that you can’t have embedded data structures like you can with MongoDB. The advantages of NoSQL over relational databases include: These are the most common data structures used by NoSQL databases: No SQL databases generally compromise consistency of writes/reads with availability and speed. Some of the main features that determine the performance of MongoDB include: Underpinning the performance of DynamoDB you’ll find: AWS DynamoDB supports Key-Value queries. Difference between AWS DynamoDB vs AWS DocumentDB vs MongoDB? The name was derived from Dynamo, a robust key-value developed by Amazon in 2004 to deal with frequent outages during the peak holiday seasons. NoSQL is pretty much what it sounds like: databases that don’t use SQL. DynamoDB’s database local persistent store is a pluggable system, where you can select storage depending upon the application use. NoSQL databases are often used in big data and real-time web applications. MongoDB stores data in JSON like documents. A chunk of the differences between Cassandra & Dynamo stems from the fact that the data-model of Dynamo is a key-value store. Users can get started with DynamoDB with virtually no upfront cost. Provisioned Capacity Mode – user specify the number of reads & writes per second that their application will require. In this blog, we’ll look at factors of cost, security and ease-of-use. ... On the other hand, HBase can be a very good solution for write-heavy applications and enormous amounts of records. In comparison, DynamoDB enables users to store dynamic data. On DynamoDB, Querying data can be done with a proprietary API from AWS. You’ll see from the table below that MongoDB supports many more programming languages than AWS DynamoDB. Both are utilised in numerous applications and have proven their efficiency at an unprecedented scale. Beware though that unless you’re using MongoDB Atlas, you’ll be responsible for the security of the entire stack on which MongoDB is hosted. Both data storage systems provide similar functionality, but they handle data storage differently. A NoSQL database comparison between Cassandra, MongoDB, and HBase examining differences in features, use cases, advantages, disadvantages, and community. Relaxed vs Strong consistency. MongoDB offers RBAC (Role Based Access Control), which includes standard, well defined roles, and the ability to create custom roles. If you want some advice on the best direction to go with your NoSQL database requirements, talk to a Logicata cloud expert who will be happy to discuss your specific use case and advise on the best way forward. Amazon DynamoDB X. exclude from comparison. Let’s talk about one of the most powerful databases, Amazon DynamoDB and how it compares with the best of breed open-source database Apache Cassandra. As I mentioned at the beginning of the article, the answer to this question is not necessarily an easy one. Complex queries executed within MongoDB, minimising the requirement for third party data analytics tools. Amazon DynamoDB can be classified as a tool in the "NoSQL Database as a Service" category, while HBase is grouped under "Databases". It supports on-demand pricing for these units, as well as provisioned and reserved pricing. Both of these NoSQL databases can deliver performance and high availability at global scale. These app… NoSQL databases are not relational, that is, there are no connections between tables in a database. JSON formatted documents increase speed and flexibility. In terms of Developer’s learning curve, querying data can be done with SQL like language for very straightforward data storage/retrieval requirements. DynamoDB, on the other hand, uses a shift-left model of scalability. MongoDB supports SSL and TLS encryption, and can pass through disk encryption. NoSQL databases are designed for scale, but their architectures are sophisticated, and  DynamoDB is a managed NoSQL database service provided by Amazon Web Services. In DynamoDB and Cassandra, it’s called a partition key. Once you are ready to make the switch, you simply need to update the connection string in your application code to point to the new MongoDB Atlas database. Data Structures are more flexible & make some operations faster. There’s a cascade of AWS content produced daily. Cassandra and DynamoDB both origin from the same paper: Dynamo: Amazon’s Highly Available Key-value store. The pros and cons of a database engine for your business will likely depend upon your dev team and the applications you use. MongoDB is difficult to install and configure, and there is little support available to assist with this. DynamoDB's main unit of cost is read/write capacity units. I find these simple use cases to be one of the “gateway drugs” of serverless usage. Today, AWS CEO Andy Jassy launched the first online AWS re:Invent conference via live stream from Seattle. SQL, NoSQL and DynamoDB . The name comes from Dynamo , a highly available key-value store developed in response to holiday outages on the Amazon e-commerce platform in 2004. The biggest question is whether you want to set up, maintain and monitor your own cluster or will AWS do that for you. MongoDB runs on multiple cloud platforms, scales horizontally across geographies, and has extensive performance monitoring capabilities. The cost structure for both of these AWS NoSQL databases is also different. DynamoDB is … Rich monitoring and real time performance dashboards give great visibility into database performance. Amazon DynamoDB. Automated sharding, horizontal scaling, optimum data location to ensure low latency database writes from any geographic region. Mongo DB provides a number of powerful ways to analyze data, including: MongoDB is designed from the ground up to be a distributed database, which means that high availability, horizontal scaling and multi region distribution all come as standard and are easy to set up. Dynamo’s data model is quite simple, represented by binary objects identified by a key. DynamoDB is a proprietary NoSQL database service built by Amazon and offered as part of the Amazon Web Services (AWS) portfolio. Cassandra is considered a wide-column store, which manages data in column families. This pricing model works best for unpredictable application traffic, but ultimately may be more expensive. You can find a full description on Wikipedia, but let me summarize here. For these simple applications, DynamoDB is a perfect fit. I’m not a database guy, I’m a node guy. MongoDB can be hosted anywhere – any public or private cloud, or on premises datacenter. At the same time, Cassandra is designed as a column-family data store.
