Design Patterns for Deployment Strategies

All IoT deployment requirements are not the same. They dier by many variables and there is no

single best solution available. Following deployment strategies serve dierent needs.

Single Environment Deployment Pattern

Problem

For small IoT projects, it is important to have less complexity in the deployed environment

so speed, security and reliability won’t get aected. Sometimes, speed and reliability are more

important than scalability as the scope of the project is very limited to one particular area. In

this case complex deployment will not work.

Solution

For such problems, single environment deployment pattern is more useful as all the nodes are

located in close proximity of each other. This ensures the speed of communication and reliabil-

ity as single and data loss possibility is reduced down to none. Single environment also brings

a lot of benefits as the tasks such as installation, configuration, and addition of a new node are

very easy to manage with less resources in hand.

Heterogeneous Deployment Pattern

Problem

For larger IoT deployment, single environment deployment does not work as it brings a lot of

problems like limited computing resources, inadequate networking capability, and shortage of

storage. Also, these types of IoT deployments have limited geographical reach and availability.

Solution

Using multiple distinct infrastructure environments or regions called Heterogeneous

deployments can easily solve this problem. Heterogeneous deployments are also known as

“hybrid”, “multi-cloud”, or “public-private”. These environments span regions in the local and

public cloud, or various public clouds or a single cloud.

Distributed System Deployment Pattern

Problem

For some organizations such as banks and government secret agencies, even for a large scale IoT

deployment, it is important to keep data in a private environment with full control on storage

and management of the physical servers. For such purposes, neither single nor Heterogeneous

Deployment is suitable.
