The layers of platforms start at the bottom with hardware choices such as which CPU architectures and vendors you want to use. The next layer is operating system platforms, what flavor of Linux, what version of Windows etc.

We were able to meaningfully improve both the predictability and performance of these containers by taking some of the CPU isolation responsibility away from the operating system and moving towards a data driven solution involving combinatorial optimization and machine learning. For services, the gains were even more impressive.

… to realize these insights, hardware needs to access data at object granularity and must have control over pointers between objects. Hotpads is a hardware-managed hierarchy of scratchpad-like memories called pads. Zippads also has the best reduction in main memory traffic : halving the amount of traffic compared to the baseline.

Essentially, all traffic between China and the rest of the world goes through a few national level and a handful of core level access points in different regions. The censorship and monitoring of internet have evolved from anti-virus-like and firewall software to hardware security patches for all devices that uses internet.

Software and hardware components are autonomous and execute tasks concurrently. Concurrency refers to the system’s ability to carry out multiple tasks in parallel and manage the access and usage of shared resources. It is also one of the four golden signals of monitoring, which also includes traffic, error, and saturation.

Failures are a given and everything will eventually fail over time: from routers to hard disks, from operating systems to memory units corrupting TCP packets, from transient errors to permanent failures. This is a given, whether you are using the highest quality hardware or lowest cost components. Primitives not frameworks.

Additionally, end users can access your site or applications from anywhere in the world using different browsers, operating systems, and mobile devices, all with varying connection speeds. It helps assess how a site, web application, or API will respond to various traffic, without adding any additional infrastructure.

We are used to instances of software running on different computer systems as long as some basic requirements are met (e.g., same instruction set architecture, same operating system, etc.). Similarly, we expect that most computer systems can read (and write) data that is stored in some memory.

Monitoring errors on the front-end requires a bit more work because front-end performance is highly dependant on the user’s hardware, software and connection. BrowserStack and Usersnap are ideal tools for manual error tracking because they both run on the majority of operating systems and browsers.

SQL Server According to Bob

DECEMBER 18, 2018

kernel additions to the Linux XFS file system can send the Fua bit along with the write request so “forced flush” behavior is not needed and the performance of writes is significantly improved. Testing shows that by using the Fua bit with the data, write request can reduce the I/O traffic by ~50% for a SQL Server, write-intensive workload.
