When should I consider upgrading instances and adjusting their configurations?

1. Detect, Diagnose, and Resolve Performance degradation

Performance degradation can occur due to various factors, such as increased load or outdated hardware. If the application’s performance drops significantly and persists despite optimisation efforts, it’s time to consider upgrading the infrastructure to improve overall efficiency. Performance issues may manifest as slower response times, increased latency, or frequent timeouts. By identifying the root cause and making necessary adjustments, you can restore optimal performance and ensure a positive user experience.

For instance, consider a payroll application that accumulates historical data over time. To ensure optimal performance, it’s crucial to design the application’s infrastructure in a way that can handle the increasing volume of historical data without degradation. As the system processes and stores employee data over time, it’s essential to implement efficient database management and data storage practices. By utilising a scalable database solution, such as a NoSQL or cloud-based database, the application can easily accommodate the growing historical data without experiencing performance bottlenecks.

2. More Clients, More Traffic: What You Need to Know

Let’s imagine you are the owner of a B2B SaaS application. Any new client addition is expected to bring a significant increase in user traffic, according to the size of the new client. To ensure your application can handle the increased user traffic without any hiccups, you should take proactive measures to enhance your instances and configurations.

More Clients, More Traffic: What You Need to Know

By examining past data or employing predictive analysis, you can accurately evaluate the expected rise in traffic. This foresight will allow you to make necessary adjustments and optimise your application’s performance, ensuring a smooth and satisfying user experience even during peak times.

3. Anticipate Scalability Needs

Imagine you own a newly launched social media application. You must be thrilled to witness its increasing popularity in the market. As your user base grows steadily, you understand that application’s user traffic will see a notable upward slope. To ensure the continued success of your platform, it is paramount that your application remains highly scalable and capable of handling any exponential increase in traffic without disruptions.

Anticipate Scalability Needs

On the other hand, imagine you own an e-commerce company planning to conduct a promotional event in the upcoming week. This includes huge discounts to attract users. Naturally, the user traffic will be high as the event day approaches. The application’s scalability should be scalable enough to handle the sudden spike that it will be experiencing during the event and behave normally without any disruptions.

Anticipate Scalability Needs

With reference to both the above cases, the user base of the application is either going to increase gradually or could witness sudden spikes as the day of the event approaches. To handle scalability needs, you need to move your infrastructure to a cloud platform like AWS or Azure. This lets you easily adjust resources and settings according to user demands and allocate resources as required.

4. Meet new feature requirements

Does your application require additional memory and processing power to meet its demands? Are there specific features within your application that necessitate specialised infrastructure to function optimally?For example, an auction platform decides to introduce live streaming capabilities to its application as they are planning to increase the horizons of its participants. To support this new feature, they upgrade their instances and configurations to handle the additional processing power and bandwidth requirements associated with real-time video streaming, ensuring smooth playback and a seamless user experience.

5. Technology advancements

One of the crucial factors that prompt the need for updating instances and configurations is when the current infrastructure reaches the end of its support. As the infrastructure gets depreciated, it becomes essential to reassess and update the configurations to maintain a reliable and supported infrastructure.By staying proactive and updating configurations before it gets depreciated, you can ensure continued infrastructure support and mitigate potential risks associated with running on outdated or unsupported infrastructure. This practice helps maintain the stability, security, and longevity of your application while enabling you to capitalise on the latest advancements in technology.
