1.IBM acquires Red Hat to find another way in the crowded cloud market

Red Hat was one of the pioneers in commercializing open source software, using a model in which the code was made available to other companies for free for redistribution and modification. Open source software has gradually become the cornerstone of many application systems, even in large enterprises, such as the Linux operating system, Web browser Firefox and big data analysis software such as Apache Hadoop.

However, many companies have struggled to make money from free software, as evidenced by the recent announcement of a merger between Cloudera and Hortonworks, two open source-based big data companies. Red Hat has been seen by the industry as a model for providing services and support to open source software in a financially sustainable way.

In the early hours of this morning, IBM offered to buy Red Hat for $190 a share, more than a 60 per cent premium to Red Hat's closing price on Friday. The $34 billion deal is the largest in IBM's long history and the third largest in the history of the US technology community. The hefty acquisition also shows that IBM attaches great importance to the company, a computer and services giant that has been committed to making its cloud application platform more attractive to developers for years, and Red Hat is expected to immediately add credibility and reputation to it.

"Red Hat is expected to make up for the fact that IBM is not popular with developers," said Stu Miniman, an analyst at market research firm Wikibon. " In addition, "IBM immediately consolidated its position in today's multi-cloud space," he said.

Indeed, the move reflects how difficult it is for IBM to keep pace in the era of cloud computing. It recently released quarterly earnings, showing a decline after several consecutive quarters of large revenue growth, which surprised investors. Cloud giants such as AWS and Microsoft have snuck ahead of traditional hardware and software vendors such as IBM and HPE by providing computing, storage, network resources and applications (often from open source) as an online service.

However, IBM paid a premium for the darling of the open source world, indicating that it is focused on making a bigger difference in the cloud computing industry. "the acquisition of Red Hat is a game-changing move," Ginni Rometty, chairman and chief executive of IBM, said in a statement. "it changes everything in the cloud market. IBM will become the world's number one hybrid cloud provider, providing the only open cloud solution for corporate enterprises, thereby fully exploiting the value of cloud for customers."

In particular, Rometty points out that most companies still only cover about 20% of their journey to the cloud. "the remaining 80% are aimed at discovering real business value and driving growth," she said. This is the next chapter in cloud computing. This requires moving business applications to the hybrid cloud, extracting more value, and optimizing all aspects of the business, from supply chain to sales. "

Anticipating concerns that the acquisition could jeopardize Red Hat's attractiveness as a platform-independent open source software provider, IBM said it would "remain committed to Red Hat's open governance, open source contribution, participation in the open source community and development model, and continue to build its extensive developer ecosystem." In particular, IBM says it is committed to open source work or projects, such as Patent Promise, GPL collaboration commitments, Open Invention Networks (OIN), and LOT networks.

IBM also solemnly promised to maintain partnerships with AWS, Microsoft's Azure Cloud, Google Cloud, Alibaba and other companies. Red Hat will become part of IBM's hybrid cloud team as a "separate department", maintaining the independence and neutrality of Red Hat's open source development traditions and concepts, maintaining the current portfolio and product launch strategy and unique development culture, with headquarters also in Raleigh, North Carolina, to maintain the original brand.

two。 The first Apache micro-service top-level project in the industry | Huawei graduated from open source ServiceComb

The Apache Software Foundation (hereinafter referred to as Apache), the largest open source software foundation in the world, announced on October 24th Beijing time that Apache ServiceComb graduation has become a top-level Apache project.

ServiceComb was donated to Apache by Huawei and started incubation in November 2017, and then incubated by members of the incubator management committee under the guidance of Apache mentors; on September 25, 10 votes in the Apache incubator passed an one-time graduation proposal; on October 17, the Apache board of directors passed the ServiceComb graduation resolution, which is also the industry's first micro-service project to incubate and graduate to become a top-level project in Apache.

As an one-stop micro-service solution, Apache ServiceComb consists of 3 sub-projects:

Java-Chassis

An out-of-the-box Java micro-service SDK consists of four parts: service contract, programming model, running model and communication model, as well as a set of micro-service governance capabilities, such as load balancing, fault tolerance, current limitation and call chain tracking. Micro-service governance and business logic are isolated.

Service-Center

An Etcd-based, high-performance, high-availability, stateless, Go-based service discovery and registry center that provides real-time service instance registration, real-time service instance notification and inter-service contract testing

Saga

Provide the final consistency solution for distributed transactions and solve the pain point problem of micro-service.

Highlights of Apache ServiceComb include:

Asynchronous kernel

Synchronous and asynchronous model programming based on VertX effectively ensures that high performance and low latency are maintained in traditional enterprises or e-commerce, as well as in emerging enterprises such as the Internet or the Internet of things, so as to avoid avalanche effects when peak loads are reached.

Out of the box experience

Micro-service projects launched by developers through the scaffolding website http://start.servicecomb.io can combine service registration, discovery, communication, and micro-service governance capabilities with default centralized configuration.

OpenAPI

Automatic code generation, isolation of business logic code and governance capabilities enable DevOps Pipeline, and the bi-directional generation capabilities of contract files and OpenAPI enable different teams to develop and manage code, test, and document efficiently and independently.

In 2015, Huawei Cloud launched services related to microservices, which is the original code of ServiceComb. Apache ServiceComb is the core of Huawei's cloud micro service engine CSE. It is widely used in Huawei consumer cloud, Huawei cloud core, Huawei EI and many other major products, and is the de facto standard of Huawei micro service. Huawei Consumer Cloud is based on Apache ServiceCom's high-performance, low-latency asynchronous technology to implement more than 1500 node-level micro-services, supporting 400 million mobile phone users online. Using ServiceComb,QPS increases + by 2 times and reduces latency by 45%.

3.CNCF hosts the first container runtime security project

CNCF hosts the first container runtime security project, Falco, to protect running containers in a production environment. The Falco project was originally the core instrument technology of the Sysdig open source monitoring platform, and was later donated to CNCF by Sysdig.

Falco project features:

Leverage the Linux kernel to provide runtime security at the application, file, system, and network levels (reducing detection and response time for container and micro-service architectures)

Links to other CNCF projects, such as Fluentd logging project, Kubernetes Container orchestration projects (this link will allow Falco to take steps to deal with security threats and isolate related Kubernetes nodes)

Access metadata through the Kubernetes API server (providing more detailed data collected from the Linux kernel).

Dan Kohn, Executive Director of CNCF, said: "Falco provides * * and anomaly detection for cloud native platforms, including Kubernetes, Mesosphere and Cloud Foundry. When Falco is used with other cloud native projects, such as Fluentd,Nats,rkt, Falco can provide a complete container runtime security solution."

4.Spinnaker 1.10 enhances Kubernetes automated deployment, eliminating the need for complex Manifests deployments

By Google and Netflix Inc. The jointly developed multi-cloud continuous delivery platform Spinnaker has released version 1.10 with the addition of Kubernetes vendors (Kubernetes Provider) and the integration of Helm suite manager to allow users to generate Manifests with templates. Through Istio's support for flow control, it makes it easier to automate the deployment of containers and Kubernetes.

Google mentioned that in the Kubernetes environment, continuous delivery is still in the early stages, while the release engineering team in the enterprise wants Spinnaker to provide a software delivery framework with best practices, and for organizations that are just starting to use Kubernetes, they also expect to get the resources they need to design the right environment.

So in Spinnaker 1.10, Google worked with the community to redesign Kubernetes support to abstract the complexity of managing Kubernetes Manifests, allowing developers to put more effort into their development work. The release engineering team now has access to complete Kubernetes resources through Manifests and automates the low-level complexities of managing Manifests, such as correctly handling tags or providing a tailored user experience for non-experts.

The release engineering team can design its own Kubernetes usage for the enterprise and package the work pipeline into the most commonly used path for release to other development teams, which will keep the development team away from complex scripts and low-level Manifests operations, but can also continue to use all the features of Kubernetes.

In general, there are two ways to automate the deployment of applications to Kubernetes. One is to use a generic scheduler (Orchestrator) such as Jenkins to write a deployment process to control application deployment, and the other is a relatively new, Kubernetes-based continuous integration and continuous delivery tool. Google pointed out that scripts written by general scheduling software are error-prone, and both approaches require developers to study Kubernetes Manifests in depth, but this will create bottlenecks in large-scale deployment.

The new Kubernetes vendor in Spinnaker 1.10 provides a variety of features to solve existing problems. Kubernetes vendors can automatically grab the correct Manifests for the container image files to be released, and support the repository layout and control flow of GitOps programs. It also generates multiple Manifests for development, QA, and production phases in the work pipeline, and supports Helm or other template engines.

The Kubernetes provider automatically sets the version of the container image file in the deployed Manifests, and in best practice, it uses Digests instead of Tags to avoid complex scripting operations. In addition, the release engineering team is given the ability to restrict developers' access to Kubernetes namespaces, clusters, and resource types.

Google mentioned that Spinnaker 1.10 is an important milestone in the continuous delivery and automation of software delivery work pipeline, and users can now obtain Spinnaker support for Kubernetes in Codelab.
