EnvoyProxy 2: Microservices and Routing

Abstract In part 1 of this series of articles on EnvoyProxy, a high level overview of reverse proxies, what they are for, and the internal architecture of EnvoyProxy is explained. Furthermore, the reader was made familiar with how to configure EnvoyProxy and where to find documentation to learn more. In this article, the ways in…

EnvoyProxy 1: Reverse Proxy

Abstract A proxy server is a server application that acts as an intermediary between a client requesting a resource and a server providing a resource, which typically exists at the edge of the network of the client organization. A reverse proxy sits at the edge of the network of the resource provider’s organization, and is…

Data Serialization: Apache Avro vs. Google Protobuf

Abstract For applications that need to transmit data over a network or persist data for storage into files, the topic of selecting a data serialization format is an important one. For low performance applications with small amounts of data, there are advantages to using JSON, which is highly readable by humans. However, for more complex…

Assessing Performance of Network Systems

Introduction As development of software services moves from a local development environment environment to a staging or production environment, a common concern that arises is to know the limits of what the system can handle in terms of performance. Knowledge of what your system can handle is useful for several reasons: Performance numbers are often…

Perspectives on Software Performance

Early decisions in system design can have long-term consequences which are hard to change later on. The changes to the system made in response to growing load are rarely given careful consideration, as they are frequently implemented during an emergency so severe that it can no longer be ignored. The ultimate result is a system that becomes increasingly complex, hard to work with, and costly in both hardware and engineering-hours needed to make changes.
