How We Scaled API Performance in a High-Load System and Avoided CPU Overload

Thanks to current capabilities, coders and programmers don’t have to make a bunch of unnecessary edits and rewrite parts of the project. This helps to make the code cleaner, and the speed and quality of the web servers is optimal. The specific character of high load software development systems lies in the fact that you cannot work with them like with any other system.

The unit is crafted to work ahead of the operator and line up the subsequent pick for the maximum throughput. Totes can be sent over to an ergonomic turntable picking station or handled automatically through an inbound and outbound conveyor. This saves up to 85% of your floor space, making VLMs an excellent technology choice for manufacturing businesses with varying inventory sizes. Consisting of a series of carriers attached to a chain drive, a motor drives the bi-directional travel of the carriers in a vertical loop around a track, much like a Ferris wheel. They quickly and safely deliver slow to medium velocity items to an ergonomically positioned work counter at the operator’s command. Offering compact solutions to briefly hold off incomplete orders waiting for additional items before shipment.

Deployment And Monitoring: Ensuring A Successful Launch

This helps pinpoint failures and breaking points under high-load conditions and, unlike regular performance testing, covers unpredictable behavior outside the scope of standard testing key points. Most mobile applications depend on back-end infrastructure for their success. They are coded using programming languages and may only depend on fundamental architecture solutions and best practices. They cannot manage high user requests and provide high data processing rates without a high load system. It is recommended for startups to develop apps with a scalable architecture.

  • Before performance testing, it is important to determine your system’s business goals, so you can tell if your system behaves satisfactorily or not according to your customers’ needs.
  • There are many excellent open source solutions out there, like JMeter, Taurus, and Gatling.
  • After the equipment is installed comes the costs connected with implementing the new technology with your current processes.
  • Load average represents the average load on a CPU during a specific time interval.

You might be surprised, but the numbers are not the point here at all. As you can see in the highlighted region, the load average for the last minute is 0.14. For the last five minutes and fifteen minutes, the Load Average values are 0.12 and 0.05 respectively. The glances tool is a system monitoring tool which works similar to the top command. To use the glances tool on your system, you need to install its package using this command.

What Is a Highload Project?

Load balancing is a fundamental high-availability component of such areas. It helps minimize downtime and maintain system stability at all times and brings content geographically closer to users. When selecting your deployment environment, always factor in failover, backup and recovery mechanisms suitable for handling large numbers of concurring users without performance degradation. You need to perform comprehensive testing by emulating combinations of system events and user flows to see how the app withstands various stress levels and disruptions.

Also, the customer can choose the three requests per second option for a prototype and then add scaling and debugging to it. The type of scaling you choose should depend on the requirements for your system and the issues you need to solve by scaling. This technology helps customize ad impressions for your audience, analyzes large amounts of data fast and error-free, and much more.

You can use the dashboards provided by the performance testing tool or you can look at solutions like APMs for more information. Scalability tests measure how an application can scale certain performance test attributes up or down. When running a scalability test based on a factor like the number of user requests, testers can determine the performance of an application when the user requests scale up or down. Run stress tests against your website or app before major events, like Black Friday, ticket selling for a popular concert with high demand, or elections. We recommend stress testing every once in a while so you know your system’s endurance capabilities.

API requests are distributed between several workers and AWS instances, giving them enough time to provide a response. Under peak load, we can create additional instances and avoid system crashes. Using an example from our development team, we’ll tell you how we design such solutions.

Starting a Software Development Project: A Customer’s Journey

Usually, you only need to keep one machine running for domain development. Here’s an example of our proposal for a system that processes 3, 30, and 300 requests per second. This comparison helps the customer choose between an affordable cloud environment and rich scalability options.

For 15+ years we are connecting highly skilled professionals from all over the world to share their experience, to discuss hottest topics,  to learn and to network. We are happy to invite international IT-community to join HighLoad Armenia. HyperJar is a FinTech platform that reimagines finance management by providing a user with a network of mini-accounts each of which is tailored to the user’s plans, lifestyle, and relationships.

Performance and stress testing

Thanks to this architecture, there is no central server that controls and coordinates the actions of other nodes, and, accordingly, each node of the system can operate independently of each other. These systems do not have a single point of high load systems failure, so they are much more resilient to failure. Another method to prevent failures is to increase the redundancy of individual system components to reduce failure rates (redundant power supply, RAID — redundant array of disks, etc.).

Stress tests examine how the system behaves under intense loads and how it recovers when going back to normal usage. Are the KPIs like throughput and response time the same as before spike in load? Stress tests also look for eventual denials of service, slowdowns, security issues, and data corruption.

Can you provide examples of successful high-load systems that your company has developed and deployed?

Most business owners do not quickly understand the essence of developing a high-load system. When running projects, their priority is saving money; they are not keen on spending real money on functionalities without direct returns. The intellection of high load systems came to life almost a decade ago. But, despite this fact, not many people understand what this is, or why it is essential.

Knowing about the problems of scaling and the increasing load on the integration layer, we work out the most economical long-term developing high-load apps strategy in advance.Why is it important? Let us consider an example of the wrong strategy, when it is decided, if the need arises, to horizontally scale some part of the system infinitely. The rigidity of the system solves the problem of increasing resource costs, and devops engineers do their best to balance the high app performance of the system and the capital budget.

Hence, the vertical lift modules store the trays dynamically, barely an inch apart, to optimize storage density. VLM is the most flexible technology of this category that is engineered to adjust automatically when there’s a change in inventory. These enclosed dynamic storage solutions comprise 2 columns of trays, capable of managing up to 2,200 pounds. This particular type of ASRS can handle cases and items with a maximum weight capacity of 2000 pounds per carrier.
