how does amazon dynamodb work

Amazon DynamoDB is a managed, NoSQL database service With Amazon DynamoDB service you're replacing Oracle RAC, a SAN, a team of DBAs, operations team, managers, sleepless nights and that empty feeling you get when you spend a million dollars before getting one customer. Q: What is Amazon DynamoDB? If your DNS goes down, then you don't exist on the Internet. This is key for part of our NoSQL datastore. Since Dynect and UltraDNS are specialized DNS hosting providers, they presumably have more sophisticated systems than Amazon has. Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key-value and document data structures and is offered by Amazon.com as part of the Amazon Web Services portfolio. DynamoDB is a fast and flexible nonrelational database service for any scale. For example: we wanted to manually maintain consistency of order variable in a JSON array i.e. Using DynamoDB streams, any update/delete or new item on the main table is captured and processed using AWS Lambda. To minimize points of failure. For more details about this architecture, see the blog post Indexing Amazon DynamoDB Content with Amazon Elasticsearch Service Using AWS Lambda. Like any other AWS product, Amazon DynamoDB was designed for failure (i.e., it has self-recovery and resilience built in). Shortly after the date and time of the specified timestamp, DynamoDB deletes the item from your table without consuming any write throughput. Lambda makes appropriate calls to Amazon ES for indexing the data in near real time. Technically, DynamoDB is a fully-managed , NoSQL , key-value and document-based database. Amazon DynamoDB is a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale. It is a fully managed database and supports both document and key-value data models. Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. Using a database like DynamoDB, you don't need to work with physical disks, you simply ask the database to write and read data for you, it will make sure things work correctly under the hood. Here are ten key features that helped make Amazon DynamoDB into a giant. DynamoDB enables customers to offload the administrative burdens of operating and scaling distributed databases to AWS so that they don’t have to worry about hardware provisioning, setup and configuration, throughput capacity planning, replication, software patching, or cluster scaling. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications. DynamoDB can be used pretty much in most places where you would use a SQL datastore. Amazon DynamoDB Time to Live (TTL) allows you to define a per-item timestamp to determine when an item is no longer needed. Amazon DynamoDB as managed database will work for you if you prefer code-first methodology. That makes DynamoDB a highly available, scalable, and distributed data store. DynamoDB does not offer any sort of database functions or triggers that would help manipulate the data before performing a transaction. 's Features. DNS is critical. You will be able to easily scale it if your application inserts data … Amazon DynamoDB. DynamoDB exposes a similar data model to and derives its name from Dynamo , but has a different underlying implementation. Automated Storage Scaling – There is no limit to the amount of data you can store in a DynamoDB table, and the service automatically allocates more storage, as you store more data using the DynamoDB write APIs 1.
