In an era before virtualized infrastructure made allocating additional server resources much easier, Public102 became somewhat of a "junk drawer" server. Public102 was nearly overloaded, and at the same time, it needed an OS upgrade because Windows 2000 was nearing the end of extended support. And so we started it all again.

bpftrace uses BPF (Berkeley Packet Filter), an in-kernel execution engine that processes a virtual instruction set. BPF has been extended (aka eBPF) in recent years for providing a safe way to extend kernel functionality, and has become a hot topic in systems engineering, with at least 24 talks on BPF at the last Linux Plumber's conference.

I have been making the same recommendations about tempdb since I started working with SQL Server over 15 years ago, when I was working with customers running version 2000. The latest adaptation by the SQL Server team is moving the system tables (metadata) for tempdb to In-Memory OLTP (aka memory-optimized). Now that 2019 CTP 3.2

SQL Server relies on Forced-Unit-Access (Fua) I/O subsystem capabilities to provide data durability, detailed in the following documents: SQL Server 2000 I/O Basic and SQL Server I/O Basics, Chapter 2. Durability: “In database systems , durability is the ACID property which guarantees transactions that have committed will survive permanently.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated. As well, very few cases are in need to have a full system/solution to provide scalability with sharding.

For example, if you want to add features such as Augmented Reality, Virtual Reality, Artificial Intelligence, and others, costs of creating an app might go up. On the other hand, hybrid app development is all about developing an app that works and functions on multiple operating systems such as Android, iOS, and Windows.
