At QCon London, Sarah Wells presented “Avoiding Alerts Overload from Microservices”, and cautioned that developers and operators must fundamentally change the way they think about monitoring when building a microservice system. Key takeaways included: build a system that can be supported; focus on ‘stuff that matters’ when creating monitoring and alerts; and cultivate and improve alerts.
Spotify clients generate up to 1.5 million events per second at peak hours and all are handled by their Event Delivery System, designed to have a predictable latency and to never lose an event, Igor Maravic noted in his presentation at the recent QCon London conference, where he gave a high level overview of the system and some of the key operational aspects.
At the company’s recent InterConnect conference, IBM announced the release of IBM Blockchain as a Service. This service is based upon the Linux Foundation’s Hyperledger Fabric version 1.0 and runs on IBM’s high security network which is underpinned by LinuxONE. Previously, the Hyperledger Fabric was in an incubator state and has since been promoted to an active state.
Since the beginning of 2017 the Cloud Native Computing Foundation (CNCF) has added three new projects to their portfolio for hosting and stewardship, including: linkerd, a transparent proxy ‘service mesh’ that provides service discovery, failure handling and visibility; gRPC, a language agnostic high performance RPC framework; and CoreDNS, a fast and configurable cloud native DNS server.
Former technical leaders from Twitter and Couchbase have created FaunaDB, a new general-purpose database.
HelloFresh recently migrated their applications to a new API gateway with zero downtime. Their Director of Engineering, Ítalo Lelis de Vietro, shared the challenges and the migration process in a recent article.
At QCon London, Matt Heath, Distributed Systems Engineer at Monzo Bank, presented “Building a Bank with Golang”. Key takeaways included: Golang’s focus on simplicity and readability in combination with excellent concurrency primitives making this a language well-suited for creating “high volume, low latency, distributed applications”.
Arnon Rotem-Gal-Oz believes that something is either a monolith or a microservice is nonsense. He also believes that more and more implementations which claim to be microservices will not live up to all of the principles. However, he does not discount the need for semi-independently deployable software components and discusses an approach he has found useful, which he call Aspects.
Deliveroo has grown dramatically the last years, both in terms of business and IT, and is facing a lot of technical challenges with its large monolithic application. The solution is to go distributed, but without microservices, Greg Beech noted in his presentation at the recent QCon London conference, describing their move from a monolith into a distributed system.
The world is concurrent with everything around us asynchronous and event oriented. Concurrency and the cloud are things every developer will have to deal with in the future, Joe Duffy claimed in his keynote at the recent QCon London conference. At the heart of this is communication, which is essential both for concurrent and distributed systems.
Bouyant, a cloud-native services company, announced the one-year anniversary of Linkerd, an open source “service mesh” project for cloud-native microservices-based applications. William Morgan, founder and CEO of Bouyant, spoke exclusively to InfoQ about this milestone.
The newly formed Enterprise Ethereum Alliance has published a Vision Paper outlining “a vision for users and stakeholders to propose, implement, and integrate advances to the Ethereum protocol with support for Enterprise Ethereum protocols.” In this paper the EEA discusses many topics related to Pluggable Consensus, interoperability, Ethereum protocol updates, storage and performance.
At QCon London, Jonas Bonér, CTO at Lightbend, presented “From Microliths to Microsystems”, and explored microservices from first principles, and discussing the architectural style in the context of distributed systems. Key takeaways included: avoid building ‘microliths’, and instead create systems that are resilient and elastic; and practice events-first Domain-Driven Design (DDD).
Google has made public an API Design Guide for creating HTTP or RPC APIs. These design principles are recommended especially to developers creating gRPC APIs connecting to Google Cloud Endpoints.
In a recent blog post, Microsoft announced their participation in the newly formed Enterprise Ethereum Alliance. The mission for this alliance is to learn from and build upon the only smart contract supporting blockchain currently running in real-world production and to define enterprise-grade software capable of handling the most complex, highly demanding applications at the speed of business.
