Web Applications, Infrastructure and Security training

Print Friendly, PDF & Email

This Web Applications, Infrastructure and Security training offers a unique overall view of Web Applications, Infrastructure, Architecture and Security, in stead of attending multiple product specific courses. It explains the dependencies and relationships between the different components and you will learn the essentials of each component.

This training is available as a classroom training as well as a webinar: live connected to the instructor using Skype or Zoom.

This Web Applications, Infrastructure and Security training is meant for:

  • for DevOps engineers who need more knowledge of infrastructure (hybrid cloud), design and security and be prepared for the “shift left”.
  • For Infrastructure specialists who need more knowledge of software development, for example client-side development/Javascript, Java or continuous integration.
  • For Managers and Product Owners  who need more technical knowledge.

This Web Applications, Infrastructure and Security training (6 sessions of 4 hours) offers the essential knowledge to understand the complete application chain. It provides insight in Web Applications and the necessary infrastructure. You will learn important architectural principles as security (including High Availability) and SOA (REST API’s, microservices, loosely coupled etc. etc.)

This Web Applications, Infrastructure and Security course is suitable for everybody closely involved in IT: Product Owners, Customer journey experts, management and IT staff. Furthermore, there will be a higher demand for IT generalists when moving to the cloud: this course is a perfect preparation for IT engineers to migrate to the cloud.

The Cloud (self service portals) causes a shift in responsibilities: DevOps must have infrastructure and security knowledge (DevOps must own the stack, DevSecOps) and cannot fall back on an IT infrastructure department.

This Web Applications, Infrastructure and Security training answers the following questions:

  • How does a Load Balancer work, a firewall, a secure reverse proxy, DNS, etc. etc.? What’s a DMZ?
  • How can I achieve High Availability and how do I prevent losing data?
  • How does Disaster Recovery (DR) work? Why do we prefer active-active?
  • What are the consequences of migrating to the cloud and how can I avoid a vendor lock in?
  • What is a cloud native application?
  • What are the advantages of client-side development (javascript, Polymer, etc.)
  • What is a webservice (REST API’s, microservices) and loosely coupled?
  • How do I manage my application chain?
  • What are the consequences of using containers (Docker) and immutable servers?
  • What are the advantages of an event-driven architecture?
  • How do I secure my data and applications?
  • What is the importance of network segmentation?

You will learn the ins and outs of the most important middleware products and the latest trends in application development, architecture and security will be discussed.

The focus is on Changeability (integration and scalability) and Security (including high availability, disaster recovery and operational management). Complex subjects are explained using examples and case histories.

After attending this Web Applications, Infrastructure and Security training, you will have in-depth knowledge of all components part of an application chain. You will be able to apply best practices in IT architecture and security.

You can find a detailed agenda at the end of this page.

After attending this training you will receive the slides in PDF format as well as the application design best practices.
