What’s Business Logic?
Your IT systems, your various microservices, and every other digital tool or process, however complex, are designed for specific purposes and to carry out specific functions based on “business logic”, “business rules”, or put simply, the constraints of how data is meant to be stored and used in a specific business setting. What that means for your business is that every process (and micro-process, to boot) is defined by a set of rules that makes automation that much more feasible in a computerized setting. But when you have to set those rules again and again or recreate them from scratch in a complex business setting, the work can get tedious — and it can become riddled with human errors, as well. Here you can get information about The Business Logic of Microservices Orchestration.
What’s the Problem?
Between the tedium of regular editing to business logic (or the addition of new microservices that require this logic), there’s a lot that can affect you directly and waste your time and effort in the process of this type of individual implementation. There’s also another problem when considering certain types of business logic storage and implementation: not every manual translation of the logic in question will be error-free, even if the source is error-free to begin with. Instead, the more complex and more tedious your translation process is, the more likely it is to be riddled with errors from the one transcribing these business rules — whether it’s you or your most accomplished coding professionals. If errors are in the code, you have to take the time to fix these errors, and that time is money, just like the time you spend reimplementing this business logic from scratch. So, what’s the main problem? Waste. Waste of time and money, if you can’t extract business logic the right way.
What’s the Solution?
The problem with complex implementations of business logic is that there is every chance a manual transcription/translation of these rules can create errors within them, and that with those errors will come a period of self-correction that can take months, depending on the size and complexity of your business’s suite of microservices. However, there’s a simple way to fix this. All one has to do is utilize the same business logic from one microservice to the others. Translation can be automatic, if you extract this logic, this programming, from a functioning source first. That’s the magic of extracting business logic. Your business rules have core functions that determine the rest of the logic in any application, any microservice, any process. Without those rules, that core business logic, the rest of the code is useless; so, it only makes sense that if you can extract business logic from your legacy applications or adopt a method of extraction that precludes the need for legacy software, you can avoid the problems that so often come with other methods: namely, the waste of time and money.
How Can You Extract Business Logic?
While many modern businesses are migrating to a specific engine that’s dedicated to the maintenance of business rules themselves, there are legacy applications in use in various systems that retain business logic of their own. To get to the heart of this logic, you need to first identify operational logic within a microservice, to determine what is only marginally related to the essential business logic itself.
However, for those who built their various microservices into an orchestration tool, you’ll find a much better way to perform these extractions. An orchestration in microservices retains its own business logic, an overarching set of rules that dictates the logic in the various microservices to a degree that makes it easily identifiable and extractable. You don’t spend all the time you normally spend on building the logic in each individual micro-process within orchestrations. Instead, think of it like a set of rules that’s applied to all processes — the most essential skeleton of the programming that keeps your full workflow in check. Then, as you implement more specific rules — the operational logic, for example — to each individual microservice, they become an extension of your existing business logic. But thanks to an orchestration tool, you still have the ability to take the core logic and transplant it into a new microservice, a new workflow, or even a new business of yours that needs some of the same steps.
More than that, though, you have the ability to extract the business logic to improve or correct it centrally, rather than having to do so in each microservice on its own. What changes you make to the business logic only can benefit the whole workflow if you have it stored and implemented centrally — unless you plan on making the same edit manually for each micro-process in succession. If you aren’t using orchestration in microservices associated with your business, and you’re not storing your business logic on a separate engine of its own, then your business will be forced into that tedious editing when, for any reason, you need to update.
Given that many businesses even implement updates to their business logic depending on the order / request type, it’s now more important than ever to understand where your business logic is stored, how to extract it easily, and how to change that logic in ways that are conducive to business operations, rather than those that hinder it. Find something to help you to extract this logic safely and without unnecessary error; proper extraction of business logic doesn’t have to be a huge undertaking if you have the right tool.
