At Weltbild<\/a> <\/span>we are a Publishing and bookstore company with headquarters in Augsburg as well as a large multi-channel bookseller. Weltbild serves customers through online shops, direct marketing and its own branches. <\/span>To reduce costs and increase flexibility, a migration of the Weltbild webshop via AWS has taken place.<\/span><\/p>

Most companies are taking their first steps towards the cloud for a variety of reasons:<\/strong>\u00a0U<\/span>To save costs by having your own operating department in the IT infrastructure<\/span><\/span>n<\/span>, to react faster and more flexibly to future changes and to make it easier to perform generation updates of hardware. In addition, long-term capacity planning for infrastructure is not necessary in the cloud.\u00a0For these reasons, Weltbild decided to move to the AWS Cloud.<\/p>
The first implementation took place with the webshop of Weltbild.de.<\/a><\/span> A move to the cloud generally offers the possibility of lower maintenance costs and greater flexibility. However, it must be taken into account that the hoped-for change after an infrastructure move with the \"lift and shift\" mentality cannot be achieved automatically. The reality if is often quite the opposite: the realization of these desired results requires effort and prior knowledge in the area of infrastructure redesign as well as the available cloud services.<\/p>
Based on this knowledge, Weltbild initiated a new project. The main tasks consisted of (1)<\/strong> a renewed relocation of the infrastructure<\/strong>this time, however, in (2) combination with a Cloud-Redesign<\/strong> and a (3) flexible workflow<\/strong>. The biggest challenge in the implementation was the very strict deadline. If the deadline had been missed, it would have meant that Weltbild would have been bound to the legacy-cloud and would ultimately have had to pay for infrastructure that they would not use.<\/p>
This is exactly the point where our XALT DevOps team was assigned. The goal was to accelerate the planned project and bring in additional expertise related to AWS-specific Technologies as well as Infrastructure and Configuration as Code. This allowed us to ensure that the full infrastructure migration was completed on time, considering the new project goals.<\/p>

The first challenge was to define all necessary steps of the migration and to layout a roadmap. This had two purposes in the project:<\/strong>\u00a0On the one hand, the project management team receives a project overview and an illustration of identified risks that could influence the deadline. On the other hand, the project team receives defined goals that enable the project to be carried out in the given period. With this foundation, the Weltbild team could be offered the necessary support to manage the cloud migration with agile methods. Our DevOps team advised Weltbild on the path to implementation and introduced new techniques and a DevSecOps mentality<\/strong> to the team. These included:<\/p>
