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. Developing a NIC that supported single root IO virtualization allowed us to give each VM its own hardware virtualized NIC.

In this blog post, we will discuss the best practices on the MongoDB ecosystem applied at the Operating System (OS) and MongoDB levels. Operating System (OS) settings Swappiness Swappiness is a Linux kernel setting that influences the behavior of the Virtual Memory manager when it needs to allocate a swap, ranging from 0-100.

This complexity is “hidden” to the end user, like how an API (Application Programming Interface) operates, whether that is an actual user or another computer. These systems can include physical servers, containers, virtual machines, or even a device, or node, that connects and communicates with the network. Heterogeneity.

Our straining database infrastructure on Oracle led us to evaluate if we could develop a purpose-built database that would support our business needs for the long term. Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases.

A covert cache-based channel (for example) can be built by the sender modulating its footprint in the cache through its execution, and the receiver probing this footprint by systematically touching cache lines and measuring memory latency and by observing its own execution speed. virtually-addressed state must be flushed.

Likewise, object access paths must be heavily multi-threaded and avoid lock contention to minimize access latency and maximize throughput. These are areas in which we have invested heavily to take advantage of 10 Gbps (and faster) networks and to handle intermittent network delays inherent in virtual server infrastructures.
