Web app testing : Optimized for mobile browsing and server-driven, the web apps should be tested for UI to ensure that all the elements of the app are aligned for different screens and resolutions. Since the mobile apps have limited storage space and power supply, test for memory utilization as well as battery usage.

As the DB continues to run on the new host – the Nutanix storage detects the access patterns and “localizes” the data that the DB is accessing. Many different queries are executing in parallel, some hitting RAM cache, some hitting storage. Over the subsequent minutes the transaction rate increases to ~30,000 TPS.

Nutanix X-Ray is well known for being able to model IO/Storage workloads, but what about workloads that are CPU bound? This time though the metric is Database transactions per second not IOPS or Storage throughput. For our purposes we are going to use Postgres DB and the built-in benchmarking tool PGbench.

PostgreSQL & Elastic for data storage. Robert’s AWS & EKS admin team are monitoring most services with that capability but found it beneficial for them to have Dynatrace monitor Elastic File Storage (EFS). 2: Automate Quality aka “Performance as a Self-Service”. NGINX as an API Gateway. REDIS for caching.

The vertica vioperf tool is used to determine whether the storage you are planning on using is fast enough to feed the vertica database. The amount of data written is simply the IO rate achieved by the storage * runtime. The vioperf tool runs on a linux host or VM and can be pointed at any filesystem just like fio or vdbench.

We had specializations in hardware, operating systems, databases, graphics, etc. Jim Mauro and Allan Packer visited on rotation from New Jersey, and Adelaide Australia, and worked out how to produce a database sizing guide for Oracle Financials, which I wrote up and published. Jim also joined the database performance team.

Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting ? So many default to Amazon RDS, when MySQL performs exceptionally well on Azure Cloud. MySQL DBaaS vs. Self-Managed MySQL. A good example would be slow query analysis. High Availability Deployment.

It is very common to have large resource-hungry databases separated across nodes using anti-affinity rules. As with traditional storage, applications are writing to a shared storage environment which is necessary to support VM movement. The idea here is to simulate the two main storage workloads of a DB. 100% write.

Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance. As is also the case this limitation is at the database level (especially the storage engine) rather than the hardware level.

From the technical perspective, the following properties should be highlighted: All data is initially stored in the relational database, but this database is heavily loaded because it is a master record for many applications. Storage nodes are basically Coherence storage nodes.

Mounting object storage in Netflix’s media processing platform By Barak Alon (on behalf of Netflix’s Media Cloud Engineering team) MezzFS (short for “Mezzanine File System”) is a tool we’ve developed at Netflix that mounts cloud objects as local files via FUSE. Our object storage service splits objects into many parts and stores them in S3.

It is limited by the disk space; it can’t expand storage elastically; it chokes if you run few I/O intensive processes or try collaborating with 100 other users. Over time, costs for S3 and GCS became reasonable and with Egnyte’s storage plugin architecture, our customers can now bring in any storage backend of their choice.
