Improvements to backend roadmap content (#6000)

* Update [email protected] * Update [email protected] removed a biased (by Bitbucket) link and put one by a regular guy * Update [email protected] added a warning for caching * Update [email protected] - removed a deprecated article since caching is a complex topic I added links about strategies, Distributed ones and example of Hibernate 1st/2nd level caches * New content "monitoring" node * Update [email protected] * Update [email protected] * Update [email protected] added a simpler link because the link to the reference is probably not going to be read by many * added another link to [email protected] * Service mesh - fixed broken link

 An architectural pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. The architectural patterns address various issues in software engineering, such as computer hardware performance limitations, high availability and minimization of a business risk.

 # Caching
 
-Caching is a technique of storing frequently used data or information in a local memory, for a certain time period. So, next time, when the client requests the same information, instead of retrieving the information from the database, it will give the information from the local memory. The main advantage of caching is that it improves the performance by reducing the processing burden.

+NB! Caching is a complicated topic that has obvious benefits but can lead to pitfalls like stale data, cache invalidation, distributed caching etc

+Distributed systems are hard to build, deploy and maintain. They consist of multiple components which communicate with each other. In parallel to that, users use the system, resulting in multiple requests. Making sense of this noise is important to understand:
+- how the system behaves
+- is it broken
+- is it fast enough
+- what can be improved
+
+A product can integrate with existing monitoring products (APM - application performance management). They can show a detailed view of each request - its user, time, components involved, state(error or OK) etc. 
+
+We can build dashboards with custom events or metrics according to our needs. Automatic alert rules can be configured on top of these events/metrics.
+
+A few popular tools are Grafana, Sentry, Mixpanel, NewRelic etc

 Monolithic architecture is a pattern in which an application handles requests, executes business logic, interacts with the database, and creates the HTML for the front end. In simpler terms, this one application does many things. It's inner components are highly coupled and deployed as one unit.
 
+It is recommended to build simple applications as a monolith for faster development cycle. Also suitable for Proof-of-Concept(PoC) projects.
