In this project we implemented a monitoring and alarm solution to keep a near 100% uptime. One major requirement was to get alarms before customer's experience an issue. EnergiData "MinEnergi2" solution has an uptime near 100%. The solution receives consumption measurements from 10000+ of remote energy meters. These measurements are sent from every second to an hourly basis. Missing measurements due to downtime could potentially have fatal consequences for companies that required an alarm if devices consumed too little or too much energy. This could be a cooling plant for groceries, where missing consumption indicates no cooling.

As Cloud Solution Architect/Developer

I was responsible for the cloud architecture in AWS and Azure. I designed and developed an architecture to a scalable and robust infrastructure.

Exploring the Pros and Cons of Using Distributed Cache

Introduction

In this blog series we will discover on how to take advantage of caching data using distributed cache architecture. We'll dig deeper into code and tools later, where you will find a complete package of code and infrastructure that works out ouf the box. But more about that in a future blog.


In the world of modern software development, performance and scalability are crucial factors. One technology that has gained significant traction in addressing these concerns is distributed caching. Distributed caching is a technique that involves storing frequently accessed data in-memory across multiple nodes or servers to accelerate data retrieval and enhance application responsiveness. While distributed caching offers several advantages, it also comes with its fair share of challenges. In this blog post, we'll delve into the advantages and disadvantages of using distributed cache in your applications.


A client approached us seeking assistance in enhancing the performance of their ML pipeline. Each execution run was consuming hours, leading to substantial repercussions for their business operations. Moreover, this prolonged execution was adversely affecting other components of their application infrastructure.

Upon investigation, it became evident that the client was repeatedly executing the same query, despite yielding identical results on each occasion. Through the implementation of a distributed cache, we were able to achieve a significant reduction in performance overhead. As part of our proof of concept (PoC), we developed a custom predicate within a Hazelcast cluster. This solution enabled us to execute a complex query on a dataset of 15 million rows in sub seconds, in strong contrast to the minutes for executing against a database.



Advantages of Using Distributed Cache

  • Improved Performance: One of the primary benefits of using distributed caching is the dramatic improvement in application performance. Since cached data is stored in-memory, the time it takes to retrieve data is significantly reduced compared to fetching data from slower disk storage or databases. This results in quicker response times and a smoother user experience.
  • Reduced Database Load: By offloading frequently accessed data from the database to the cache, you can significantly reduce the load on your database server. This not only improves the overall application performance but also helps prevent database bottlenecks during peak usage periods.
  • Scalability: Distributed caching systems are designed to be highly scalable. As your application's traffic and data load increase, you can easily add more cache nodes to distribute the load and maintain optimal performance. This elastic scalability is crucial for handling sudden spikes in traffic without compromising on user experience.
  • Latency Reduction: Distributed caches are often deployed closer to the application servers, minimizing network latency and reducing the time it takes to retrieve data. This is particularly advantageous in distributed or microservices architectures where data may be spread across different services.
  • Caching Strategies: Distributed caching allows for the implementation of various caching strategies, such as Least Recently Used (LRU), Time-to-Live (TTL), and cache eviction policies. These strategies enable developers to fine-tune how data is cached and managed based on specific use cases and application requirements.

Disadvantages of Using Distributed Cache

  • Data Consistency: One of the biggest challenges in distributed caching is maintaining data consistency across cache nodes. If not handled properly, cached data might become stale or inconsistent, leading to incorrect results or unexpected behavior. Implementing proper cache synchronization mechanisms can mitigate this issue but adds complexity to the system.
  • Complexity and Overhead: Integrating distributed caching into an application introduces an additional layer of complexity. Developers need to design, implement, and maintain the cache infrastructure, which can lead to increased development and operational overhead.
  • Cache Invalidation: Ensuring that cached data is updated when the source data changes is crucial. Cache invalidation strategies need to be carefully designed to prevent users from receiving outdated or incorrect information.
  • Memory Management: Since distributed cache relies on in-memory storage, memory management becomes critical. Improper management can lead to memory exhaustion, affecting the overall performance of the application.
  • Costs: While many open-source distributed caching solutions are available, using enterprise-grade caching systems or managed services can incur additional costs. Balancing the benefits of improved performance against the associated expenses is essential.

Conclusion

Distributed caching offers a powerful solution for improving application performance, reducing database load, and enhancing scalability. Its ability to provide low-latency data retrieval makes it an attractive option for modern applications that require high responsiveness. However, the disadvantages of distributed caching, such as data consistency challenges, increased complexity, and potential costs, should not be underestimated.

When considering whether to implement distributed caching in your application, it's crucial to carefully assess your specific use cases, architectural needs, and the trade-offs involved. A well-designed caching strategy, along with proper planning and maintenance, can help you harness the advantages of distributed caching while mitigating its potential downsides.
