High Availability vs. Fault Tolerance: Is FT’s 00.001% Edge in Uptime Worth the Headache?

Percona

Some of the most important elements include: No single point of failure (SPOF): You must eliminate any SPOF in the database environment, including any potential for an SPOF in physical or virtual hardware. Without enough infrastructure (physical or virtualized servers, networking, etc.), there cannot be high availability.

The Ultimate Guide to Database High Availability

Percona

Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. If a primary server fails, a backup server can take over and continue to serve requests.

Machine learning systems are stuck in a rut

The Morning Paper

Systems researchers are doing an excellent job improving the performance of 5-year old benchmarks, but gradually making it harder to explore innovative machine learning research ideas. Worse, the resulting brake on innovation in languages is in itself reducing the incentive for back-end developers to improve on the current situation.

Looking Ahead Beyond CMOS

ACM Sigarch

Over the last two decades, processor designers have extracted significant performance by leveraging architectural solutions and process innovations. The low power dissipation and higher density of CMOS enabled the architectural innovations of the last few decades which led to the single thread improvements seen in the 1990s and early 2000s.

Egnyte Architecture: Lessons learned in building and scaling a multi petabyte content platform

High Scalability

To add elasticity, reliability and durability, these data centers are connected to Google Cloud platform using high speed, secure Google Interconnect network. As events are immutable we were caching them in Memcache for 12 hours but even them downloading the same events so many times from Memcache was causing network issues.
