I find that production deployments are a great place to find out how intertwined your architecture is.Ī symptom of not having proper indirection could be that components have to wait on one another for deployments. If you don’t have that level of visibility, then focus on the pain points during a production rollout. You can immediately start taking advantage of these strategies by looking for components within your system that are tightly coupled. Including levels of indirection in the short-term will pay off as the system becomes increasingly complex and would otherwise become more difficult to effectively manage. There are many others within code, infrastructure, networking, business processes, etc.

This is just one example of indirection within a software system. However, these trade-offs are typically negligible as your system scales out to more and more moving parts. Some of the trade-offs with this approach include absorbing the added complexity of introducing the queuing infrastructure and properly handling asynchronous tasks.
Documentation can be a simple diagram and a brief description of the expected message payload.This new approach has the following advantages: One of those subscribers can be a queue that is processed by the order management service, which asynchronously handles the message. Rather than having the website communicate directly with the order processing service, we can have it store the order and publish a message to inform subscribers that an order has been placed. Let's get back to our e-commerce site example and explore how adding a level of indirection, through infrastructure, can optimize the communication between teams and components. Luckily, technology has evolved to give us more powerful tools for adding levels of indirection in code, and in infrastructure, that can lessen the burden of maintaining highly detailed documents. Engineers are notoriously bad at maintaining technical documents. This strategy, although effective at times, is not scalable. And if that situation does start occurring, we mitigate that issue with tools like Confluence to ensure that the documentation lives in "one place." We typically don't want developers sending emails to each other every time there is a need to integrate two or more components. Documentation is itself a level of indirection. Traditionally, documentation provided a way for engineers to effectively communicate their deliverables to other teams.
#Indirection stickers registration#
Information on surrendering your vehicle tags is available at the link below:īring your vehicle inspection notice or vehicle registration information with you when you drive your vehicle to the DC DMV Inspection Station for inspection renewal.The breakdown occurs because of the entanglement between the two teams. If your vehicle is still registered, but you cannot have it inspected prior to the inspection expiration date, you should cancel your registration by surrendering your tags at a DC DMV service center in order to avoid inspection late fees.
Inspection fees will be charged at the time you register or renew registration for your vehicle. Therefore, if you fail to have your vehicle inspected prior to the inspection expiration date, you will be assessed late fees.
You can provide your email address online at the link below:Īll vehicles registered in DC must have a valid inspection. You will receive your renewal notice by e-mail if you have provided DMV with your e-mail address. You will receive a renewal notice 60 calendar days before your vehicle inspection expires.
