How to build new application-oriented O M management ideasGuideO M requires breakthroughs in thinking, from Ops to DevOps, from projects to products, from resources to applications. Many problems have been plagued and are being considered. Why does most CMDB projects fail? Why is O M automation rather than IT automation more discussed? Why is online problems always a black box for O M personnel? Let's take a look at these questions. Today, I would

slot cake. Why is it that there are many tools that still take this approach to communication? There are two reasons, one is that many IT teams use different tools for collaboration and monitoring, and the other is that the team does not have the habit of using a monitoring platform or collaboration tools internally. At this point, the CTO needs to work with a unified and powerful view and architecture to monitor critical IT services, be it virtual machines, physical hosts, cloud hosts, or othe

in.Trends in the development of testers1, business, many people will do "business expert", because the test has been done for many years, particularly familiar with the system, and even more than the business of the people are still familiar, he is connected to the business and IT system, we see a lot of testers have been as a new product manager, he to set the product demand, because he is most familiar with this2, technology. Technology from the very beginning to the automation, everything wi

performance testing. This information tells administrators what is going on in the running application. Some of them can even invoke the configuration management tool for self-healing. For example, Zenoss Core can reconfigure services with Cfengine, chef, or puppet on a single detection status table. A scenario for automatic fault detection and failure repair is demonstrated on the DevOps gameday. A Web application in the Amazon EC2 Data Center, whic

Guess What, you won ' t see those on your development machine, but they can and does happen in the real world. Full stack developers can work side by side with DevOps. The system should provide useful error messages and logging capabilities. DevOps

Facebook. These companies, through communication and sharing, revealing their infrastructure concepts, software practices, and data processing frameworks, have nurtured a vibrant open source software community that has evolved into enterprise technologies, systems and software architectures, as well as new infrastructure, DEVOPS, virtualization, cloud computing and software-defined networks.Inspired by Google File System (GFS), the open source distri

. MitigationGiven the attack methods we mentioned in this article, it is very important to mitigate the security problems in NoSQL deployment. Unfortunately, application-layer code analysis is insufficient to mitigate all risks. The three trends present more challenges than before. First, cloud and big data systems usually execute multiple complex applications that use heterogeneous open-source tools and platforms. These applications are usually developed by the open-source community and in most

. The editor has a plugin for most language syntax checking, linting, and refactoring tools. Git Git is the most popular source code version control system. It is server-free and you can convert any folder on your computer to a repository. If you want to share the code, there are a lot of options, like Gitlab,bitbucket and Github (and of course the code cloud). 2017, it is recommended to familiarize yourself with the git command line, as it will be useful in more scenarios than you

To tell the truth, this feature has been in the online version since November 15, and now the enterprise can also use, no additional fees ha, packaged, Microsoft has always done.Just like above, yo

Web Developer Learning Roadmap (head chart from Google)This article is from a warehouse built by Kamran Ahmed on Github. In this article, the author shares a set of learning roadmaps for his old professors to be mastered by front-end and back-end developers and Devops staff to share their views with their students.At the same time, there are any suggestions or comments to improve the author also welcome PR. So, let's look at what skills we need to Get

This article shows a map of web development skills through a large set of graphs, gives a path to web developers to take, and summarizes the friends who want to be web engineers. Hope to share with all of youIntroducedThe role of WEB development in general, including front-end, back-end and devops three roles, as a developer can choose one of the start. The left lists the technologies that these roles need together git-Version Control tools

The general flow of software projects is: design, coding, tuning, on-line. Tuning process often encounter system performance is not enough, but the performance is not good also normal, if you write code performance on the cow X a mess, may also not need so many so-called best prticace experience summed up.Recently saw a book, "DevOps Troubleshooting", the book is very thin, the content may be in other books are explained, but he summed up very well, m

. MicroServices can be expanded on demand immediately. MicroServices can be deployed on servers with low-end configurations. Easy integration with third parties. Each micro-service has its own storage capacity and can have its own database. You can also have a consolidated database. 　　　　Disadvantages MicroServices architectures can lead to excessive operations. Requires DevOps skills (HTTP://EN.WIKIPEDIA.ORG/WIKI/
