5 Essential Patterns for Building Resilient Java Microservices: A Developer's Guide

Circuit Breaker pattern isolates problematic services and prevents cascading failures and can be implemented in Java using libraries Hystrix or Resilience4j.
Service Discovery pattern allows services to register themselves and discover other services without hardcoding network locations. Spring Cloud Netflix Eureka is a popular choice for implementing service discovery in Java applications.
API Gateway pattern is a centralized place for handling cross-cutting concerns like authentication, logging, and rate limiting. It's advisable to design API gateway to handle the expected load and implement caching strategies.
Event Sourcing pattern persists all changes as a sequence of events, and it offers an enhanced audit trail and flexibility. It allows reconstruction of the account state at any point in time.
Command Query Responsibility Segregation (CQRS) separates read and write operations, allowing each to be optimized independently, and is especially useful in systems with a complex domain model or high read-write margin.
Implementing these patterns in Java microservices requires appropriate consideration of your specific use case and requires performance testing and maintaining observability in rigid systems.
Ensure security in your system with proper service-to-service authentication and authorization, OAuth2 and JWT (JSON Web Tokens) are commonly used for this purpose in Java microservices and consider using a message broker like Apache Kafka for reliable event distribution.
Container technologies like Docker and orchestration platforms like Kubernetes greatly simplify the deployment and scaling of Java microservices.
Leveraging Circuit Breaker, Service Discovery, API Gateway, Event Sourcing, and CQRS patterns, you can create robust Java microservices systems that withstand modern, distributed computing environments.
As you venture into the realm of microservices, keep learning and innovating, and remember that building resilient systems is as much about understanding patterns as it is writing code.

Performance Optimization for Django-Powered Websites on Shared Hosting

Running a Django site on shared hosting can be really agonizing, but with a few fixes here and there, you can get your site running way smoother.
Reducing server load, regular monitoring and contacting your hosting provider can help you handle the limited resources and avoid the noisy neighbor effect on shared hosting.
Flipping the debug switch off, configuring allowed hosts and caching are some tricks to make your site more secure and efficient.
Query optimization can be done by using .select_related() and .prefetch_related(), indexing your database and fetching only what you need.
Offloading static files to a CDN can improve your site's speed by freeing up server storage, and it's better to compress and optimize files to reduce sizes.
Keeping middleware lightweight reduces server strain and uses fewer resources.
Optimizing your frontend code can dramatically improve the user experience by combining CSS and JavaScript files, compressing images without losing quality, delaying image loading and enabling gzip compression.
Tools like Django Debug Toolbar, Sentry, New Relic or Google Lighthouse help in monitoring, measuring and optimizing your code, settings and site's performance.
These tricks can make a big difference in your Django site’s performance on shared hosting without spending too much money.
But if your site is still slow, it might be time to switch to cheap dedicated hosting plans.
