From failure injection testing to regularly exercising our region evacuation abilities, Netflix engineers invest a lot in ensuring the services that comprise Netflix are robust and reliable. Reliability, formally speaking, is the ability of a system to function under stated conditions for a period of time.

Continuous improvement of services is the most efficient process for all teams that are looking to improve the performance of their applications by considering all layers of their architecture. Similar to an athlete, the objective here is to have teams always push the limits to become faster and stronger.

Point solutions only provide a limited view of a company’s application architecture. This may result in unnecessary troubleshooting exercises and finger-pointing, not to mention wasted time and money.

This is an intellectually challenging and labor-intensive exercise, requiring detailed review of the published details of each of the components of the system, and usually requiring significant “detective work” (using customized microbenchmarks, hardware performance counter analysis, and creative thinking) to fill in the gaps.

Decades of poor architecture guidelines and lax developer discipline resulted in the commercial-off-the-shelf components of an ERP becoming inseparable from the custom code built around it. The exercise of assessing, modeling and dispositioning the landscape does offer valuable new ways of looking at legacy assets.

This abstraction allows the compute team to influence the reliability, efficiency, and operability of the fleet via the scheduler. Titus internally employs a cellular bulkhead architecture for scalability, so the fleet is composed of multiple cells. We do this for reliability, scalability, and efficiency reasons.

There was no deep goal — just a desire to see the maximum GFLOPS in action. The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. Instead, we found puzzle after puzzle. Some vector instructions can execute in only one of the two vector pipelines.

A basic concept of wind energy systems, it is increasingly relevant in commercial building architecture: specifically, if wind velocity can be increased through building design, the potential power that a building can derive from wind energy is considerably greater. In the aggregate, power is abstract in this definition.

Building general purpose architectures has always been hard; there are often so many conflicting requirements that you cannot derive an architecture that will serve all, so we have often ended up focusing on one side of the requirements that allow you to serve that area really well. From CPU to GPU.

Despite all of the risks that commonly befall an IT project, we still deal with IT planning as an exercise in deterministic forecasting: if these people do these things in this sequence we will produce this software by this date. As a result, management concerns itself with cost minimization and efficiency of expenditure.
