MySQL, PostgreSQL, MongoDB, MariaDB, and others each have unique strengths and weaknesses and should be evaluated based on factors such as scalability, compatibility, performance, security, data types, community support, licensing rules, compliance, and, of course, the all-important learning curve if your choice is new to you.

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. Load balancers can detect when a component is not responding and put traffic redirection in motion.

In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down. they are never really idle. I’ve written before about how to tune out retry storms.

Failover ensures that if the primary MySQL server becomes unavailable due to hardware failure or another issue, the system seamlessly switches to a standby replica. When a problem is detected, these tools automatically redirect traffic to a standby replica.

Also, in general terms, a high availability PostgreSQL solution must cover four key areas: Infrastructure: This is the physical or virtual hardware database systems rely on to run. Can you afford the necessary hardware, software, and operational costs of maintaining a PostgreSQL HA solution? there cannot be high availability.

Let’s face it – the ideal load test emulates real world traffic, yet most load testing software doesn’t come close. Today we’ll be reviewing LoadView , an on-demand load-testing platform from Dotcom-Monitor that makes realistic load testing possible without an up-front investment in hardware or software infrastructure.

Similarly, FID is often dependent on processor speed and how the device can handle all this content we’re sending to it — be it images to process, elements to layout on the page and, of course, all that JavaScript we love to send down to the browser to churn through.

Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us. Performance isn’t the (entire) product, of course. I suggest we should be conservative.

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). In a test environment, I've seen several more Linux panics in the past three years.

Options 1 and 2 are of course the ‘scale out’ options, whereas option 3 is ‘scale up’. When used in prevention mode (IPS), this all has to happen inline over incoming traffic to block any traffic with suspicious signatures. The FPGA hardware really wants to operate in a highly parallel mode using fixed size data structures.
