Summary

At the beginning of this chapter, we learned about EA, CMM, and the importance of each for maturing the organization’s EA and measuring the maturity of implemented processes and systems. After that, we looked at the components of technology architecture, such as networks, networking devices, wireless networks, firewalls, IPSs/IDSs, DNS, wireless networks, and VPNs, and their relevance as a backbone for building an IT operations center. Finally, we learned about cloud computing, cloud computing deployment models, and security considerations for implementing cloud computing.

In the next chapter, we will learn about enterprise resiliency and data life cycle management.
