Now the author holds the position of the Chief Architect of Cloud Native Competencies of the Architecture Department of Sberbank Competence. In this position, the author is engaged in research on the implementation and use of technologies that are already or very soon will become the de facto standard, such as servoless theologies and CloudEvents, and with which he shares with the reader. Also, the author, on a regular basis, evaluates existing systems and those planned for implementation in accordance with their modern standards, for example, CloudNative. About this, in the book, the author talks about the scope and guides the reader to implement them. The author pays special attention to this – finding practical solutions in the formed ecosystem that make life easier for both developers and the support service, while the customer remains interested in them. Employees gain knowledge of current technologies in which problems that are present in obsolete and retired ones have already been solved. This solves the problems of both developers and customers. The author does not dwell on any one technology that he has come across, but gives universal technologies in a systemic and practical form, or introduces the reader to the set of used ones, as the author gives the code in the languages of Go, NodeJS, PHP and Java depending on the relevance. more than 10 years of experience in various fields and in various positions allows us to highlight the relevant and popular ones, as well as undergoing training at Yandex, Sberbank EPAM and receiving many specialized certificates. The author has collected experience, both in domestic and foreign companies, both in startups and in enteprase, both creating his own co-commercial products and working in grocery development and outsourcing, producing streaming products, as well as complex proprietary software solutions… In addition to typing systems and practical help, the author gives an organizational minimum. Internally, the vision will enable work experience in various technical positions such as back-end and full-stack developer, DevOps and Team-Lead, including Software Architect. Experience of work not only as a hired employee allows us to take a look at the organizational level. The author worked both as a hired employee, but also as an individual entrepreneur and an official partner of a large supplier of mass software in Russia and the CIS (Bitrix Technology Partner), making and assembling customized and scalable solutions.

An enterprise architect designs interconnections between systems using an enterprise data integration bus, and an application architect designs the systems themselves, decomposing them into applications. The boundaries between applications are determined by the boundaries of use: development, deployment, provision to the vendor. Previously, applications were also combined by technology platforms and technologies, but with the advent of containerization, provisions can contain components created on different platforms, languages and stacks, enclosed in containers. It has also lost its relevance to the formation of boundaries based on the deployment of the application due to the fact that components (containers) are rolled out and are already being tested in the environment of other components. Ideally, a group of micro-services is grouped by function performed by the business and the team that develops it, but often business processes involve common components, which blur the boundaries of applications. This specificity has led to the emergence of a separate specialization – Cloud Solution Architect.

* direct integration (communication via API point-to-point, advantages: minimum overhead, disadvantages: two-way revision of systems is required, complexity of change management, complexity of scaling, no reuse);

* using gateways (communication through the API of an integration layer, such as a queue with a firewall, advantages: minimum overhead, unified API, disadvantages: complexity of change management, complexity of scaling, no reuse);
