Introduction to Design Architecture (Continued)

In this video, you will learn more about design architecture and the key aspects to consider.
We want to understand, within our design architecture, the security of data at rest, data in transit, and data in process. The availability considerations, things like divergent feeds for internet services, utility services, and colocation. Do we have colocation? Do we need colocation? So we’ve defined the service standards, the service levels that we want. This is how we propose to meet them technically. What architecture are we designing that is going to meet these requirements? So logically, the design architecture we’re looking for, the alignment of systems and services, blending internal and external systems, blending our existing and any new systems and services. Considering technical standards and technical compliance, we need to define and ideally, we enforce, right down to the process level.
Bear in mind, as well, our physical and our logical architecture may look very different. A logical architecture may be a single logical entity, a single security domain. A physical architecture may span a primary data centre, a backup data centre, and multiple cloud providers. So the physical aspect may look very, very different. We need to understand where our data is, we need to understand how our data integrates, any data assets we have, and any limitations and classification issues. The security levels, the security classification of individual assets may determine how we approach the design, and may limit some of the options we have. We can use metadata. Metadata is data about data to help control and influence our decision making here.
And when we’re looking at design for data services, we want to consider things like our API connectors, how secure they are providing those identity and access management services, duplication of information. Do we have any data warehouses? Do we need to use knowledge discovery services?
Physical and logical may look very different, the tiered logical architecture, and the multiple physical sites can influence our approach. If we are using multiple sites, then we need to consider the network connectivity between those sites, this may be an aspect of just bandwidth. Where we’re looking at live storage data from a SAN, we may also want to consider things like latency. How quickly and how responsive the connection is, not just the bandwidth. So again, listening to factoring in, there is a standard that we can use when considering architecture. TOGAF is probably - there are a variety of standards - TOGAF is probably the most common when we’re looking to produce technical architecture that addresses our business, functional, and technical requirements.
This is an approach to enterprise architecture, and it seeks to align requirements for the business, individual applications, the data, and also the technology. TOGAF uses an eight stage cyclical process to address architecture. And so this is an iterative process with subiterations in it. So we can use this, and strongly stresses the very congruent with what we’ve said so far during this section, strongly stresses the need for stakeholder engagement with each of those different areas.

In this video, you will learn more about design architecture and the key aspects to consider.

Design architecture seeks to understand the physical security requirements, such as data at rest and data in transit, as well as any availability considerations that need to be taken into account. The goal of design architecture is to ensure that there is alignment between systems and services offered.
