One of my favorite aspects of AWS is the large number of building blocks available to tackle a wide range of technical use cases.Amazon ElastiCache for Redisis one of those building blocks. While most often thought of for fast database caching needs, ElastiCache is quite flexible and ...
This may sound trivial, but you’d be amazed by how many expenses we had for things we didn’t need (think about all your old subscriptions 😱). Through our investigation, we unearthed a bunch of such resources: ancient ElastiCache clusters, entire databases, and an entire microservice. ...

How does an MVCC database work? While DBMS vendors are free to implement MVCC in their own ways, multiversion concurrency control usually works like this: Every database record has a version number. Concurrent reads happen against the record with the highest version ...
Examples: provisioned EC2 instances, Dynamo DB capacity units, Lambda function concurrency, RDS read replicas, Elastic Load Balancers, ElastiCache cluster size. Who does the scaling for that AWS service and how? Once you identify the AWS resources and configurations that drive scale, you have to...
How does queue depth work? The maximum queue depth that a drive can support depends on the storage interface standard it uses to connect to the host systems. The queue depth settings of the three storage interface are: Serial ATA, orSATA, devices can support one command queue with a queue...
