In order to determine compliance with the NAAQS, the ambient air must be sampled or monitored on a continuous or semi-continuous basis. This is accomplished by a national network of air monitoring stations. EPA has established and requires specific sampling or monitoring methods to be used for the determination of compliance with the NAAQS. These can be found in 40 CFR Part 50 Appendices A through N. In addition to sampling/monitoring for NAAQS, there is a need to evaluate the ambient air for other categories of pollutants, such as air toxics and compounds that contribute to visibility impairment and acid deposition, to adequately protect human health and welfare.

Summary Historically, developers independently implemented error handling, observability, and security within each application or microservice to ensure the success of inbound and outbound communication requests. However, as different teams repeated the process and coded similar functionality into each application (often using different programming languages), complexity, fragmentation, and security vulnerabilities were introduced into the environment. A service mesh addresses this problem by “outsourcing” the management of service-to-service communication requests to an out-of-process application. Typically implemented alongside the workload as a “sidecar” proxy, a service mesh simplifies and streamlines runtime operations. Comprising a “data plane” of interconnected network proxies and a “control plane” for configuring the proxies and collecting metrics, it provides a shared infrastructure layer to manage intra-service runtime communications within a distributed, microservice-based software architecture. Application agnostic and fully portable, the service mesh can be adopted by an organization to support any service written in any language or framework. Adding uniform capabilities across the environment, a service mesh provides authentication, authorization, discovery, encryption, load balancing, logging, observability, routing, and tracing.
