FaaS is the new "Black"

During 2018, the technology world reached new peaks with discussions of orchestration and containers. In 2019, while both these topics strengthen their hold on the Dev and Ops minds, new (and old) technologies jump into the spotlight with impact on developers.

Function-as-a-Service is the 2019 buzzword.

Serverless, FaaS or whatever you would call it will lead the marketing buzz parade in 2019. Every vendor will have some sort of FaaS product, project or use case and many of them will fail to add to the development and deployment value FaaS brings. During this time FaaS-based applications start creeping into production from companies who are focused on real on-demand capability without platform overhead.

Microservices change to services as small as necessary.

Microservices and the inability to deal with hundreds (or thousands) of discrete services will change the architectural view for good.  Instead of being as small as possible, services will become as small as necessary to deliver the correct functional returns. Developer teams will suddenly discover that design in services matters as much as design in communications; DevOps will rejoice in the improved ease of actually getting things to work.

Kubernetes limits start appearing.

Kubernetes rules the roost on orchestration, but 2019 will bring significant awareness of the limitations, such as self-monitoring and unapproachable configurations.  These limits will be loosely addressed via ecosystem adds and extensions. Furthermore, it will become ever more apparent that the orchestrated infrastructure itself is inapproachable and that honestly, Kubernetes is not start-up friendly. Expertise in K8s architecture and ecosystem will be in high demand and limited supply.

The death of centralized logging was greatly exaggerated.

Given the scale of modern applications, there is a trend to say that logging and log search/analytics are dead and that the only thing needed is events and monitoring. As expressed, there is a fundamental flaw in pure dependence on metrics, be they timeseries or otherwise. Or to describe the process, alerts tell you something is wrong, metrics and analytics can help indicate where something is wrong, but to determine what is wrong usually takes a dive into log files. Developers and Ops will be reminded that logs are the ultimate source of truth in production.
