For retail organizations, peak traffic can be a mixed blessing. While high-volume traffic often boosts sales, it can also compromise uptimes. Instead, to speed up response times, applications are now processing most data at the network’s perimeter, closest to the data’s origin.

With a simple example such as this, it would not necessarily be expected for the additional network traffic to be significant between the 2 approaches. However, with more complex application logic this network round trip soon becomes a key focus area for improving performance. On MySQL, we saw a 1.5X performance advantage.

Types of DBMS DBMS can be classified into hierarchical, network, relational, and object-oriented types. Data backup and recovery in a DBMS encompass a series of procedures that enable users to generate data backups as a precautionary measure and restore data in the event of data loss, corruption, or system failures.

There’s another emerging option that we didn’t talk about there: the use of far-memory , memory attached to the network that can be remotely accessed without mediation by a local processor. A key outcome of this design is that only exception events cause data transfers to the consumer, reducing far memory traffic. The last word.

When a QoS violation is predicted to occur and a culprit microservice located, Seer uses a lower level tracing infrastructure with hardware monitoring primitives to identify the reason behind the QoS violation. E.g., in memcached there are five main internal stages, each of which has a hardware or software queue associated with it.
