A CDN (Content Delivery Network) is a network of geographically distributed servers that brings web content closer to where end users are located, to ensure high availability, optimized performance and low latency. Organizations can select the most cost-effective option for each region or traffic type, reducing overall CDN expenses.4.

In such a situation I’d expect to see unusually high latencies, but normal throughput). I was only partially right (there is a steady-state queue involved)… Plus, although it’s not described, the performance degradation observed in this case would almost certainly be poor latency and poor throughput. P2 is granted L by P1.

Again, the benefit being that the code within your containers or virtual machines is managed by the cloud provider. Another factor is that serverless applications are distributed, and sometimes across different cloud platforms, making it difficult to manage in the process. The time it takes between an action and a response is latency.

As shown in the following diagram, a typical analytics system receives messages from a message hub, such as Kafka, which buffers incoming messages from the data sources until they can be processed. The complex web of communicating devices that surrounds us needs intelligent, real-time device tracking to extract its full benefits.

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. Because the solutions still rely on writing in one single node that works as Primary.

This becomes an even more important lesson at scale: for example, as S3 processes trillions and trillions of storage transactions, anything that has even the slightest probability of error will become realistic. Developing a NIC that supported single root IO virtualization allowed us to give each VM its own hardware virtualized NIC.

These systems can include physical servers, containers, virtual machines, or even a device, or node, that connects and communicates with the network. Each process has its own independent memory that it works with. This also includes latency, or the time it takes for data or a request to get through a network. No Shared Memory.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.
