We were pushing the limits of what was a leading commercial database at the time and were unable to sustain the availability, scalability and performance needs that our growing Amazon business demanded. Performant – The service would need to be able to maintain consistent performance in the face of diverse customer workloads.

High Performance I/O Instances for Amazon EC2. By Werner Vogels on 19 July 2012 12:00 AM. These include the likes of high performance computation, for which we introduced the Cluster Compute and Cluster GPU instance types. Databases are one particular area that for scaling can benefit tremendously from high performance I/O.

Investigating weird Chrome performance problems is literally my job so we started chatting. I then looked in the “Virtual Memory Snapshots” table at the Working Set column. The difference is dramatic: The performance of scanning the memory in the normal mode is quite consistent, taking about 0.2 The answer is later in this post.

What I find is very similar to backups: No DBCC CHECKDBs performed at all DBCC CHECKDBs being performed only on select databases DBCC CHECKDBs last performed months or years ago. SQL Server 2012 introduced a memory manager rewrite so that the maximum server memory value applies to all SQL Server memory allocations.

The Problem Of Unpredictable Performance. At the same time, we have a widening performance gap. In terms for performance, these phones have plateaued at the performance of a 2012 iPhone. Applications built for the Web are expected to run on devices that fall anywhere on this broad performance spectrum.

SQL Server According to Bob

NOVEMBER 29, 2016

What does this look like in a Virtual Machine? By their nature, virtual machines don’t have a concept of logical or physical processors. So the configuration of the virtual machine you setup and the capabilities of your hypervisor will dictate what the guest OS and SQL Server will detect. Hyper-V calls these vCPUs.

By Werner Vogels on 18 January 2012 07:00 AM. Amazon DynamoDB is a fully managed NoSQL database service that provides fast performance at any scale. Any downtime or performance degradation in these services has an immediate financial impact and their fault-tolerance and performance requirements for their data systems are very strict.

In addition to looking at performance differences, we also want to compare ScaleOut StateServer (SOSS) to AppFabric on qualitative measures, such as features, ease of installation, and management. Testing Scale-Up Performance. So our comments will be confined to what testing we felt was valuable and how well SOSS performed.

Note: It makes sense to use S3 as the cloud object storage solution only if we also use Amazon’s service for virtual servers on the cloud, EC2 , for running the application. Otherwise, the user may have to wait extra seconds from uploading/downloading an image to/from a distant location.
