The systems used to manage the large-scale app might end up way out of your current budget. Another advantage of having loosely connected components is that you can use different technology stacks, if needed. Since the system isn’t a monolith and you can perform work on microservices individually, failures won’t affect the entire app, only the individual component. This is a DevOps practice that allows continuously integrating code changes. It’s most useful when a project requires timely results and has multiple contributors.

Development of High-Load Systems

Reports at Highload 2021 were selected by a very strict program committee, which included the best experts in the industry. The program grid includes reports that raise important and topical issues of the industry for discussion, telling about the experience of speakers High-Load Management Systems Development or the companies they represent. Our designers made sets of stickers with references to internal IT humor, which the IT community really liked. At all conferences and meetups, they go like hotcakes, and for such a large forum, we printed a huge number of stickers.

System architectures that maintain high computing speed and uninterrupted services with short response times. PNN Soft Company provides full-cycle High Load System Development services for various spheres.

Quality Assurance Check out our rigorous QA and testing process to deliver quality apps. In the world of computer programming “load” means the amount of data that is copied from the main memory into the data registry. And in networking it means the amount of data that’s being carried out by the network or a system. A dedicated team – a well-formed team of developers who can fulfill your project objectives. It could take a lot of time to manage the cost, and before that, to research what exactly your app requires.

How To Make A Scalable Web Application: 4 Things To Consider

Or of course, you can just add code to your application with encrypted data before writing it down. In Cloudflare and like many other SaaS businesses, we prefer operating system full disk encryption for different reasons. Mostly, because it's very easy to set up and no configuration needed. Applications do not even know that they're writing encrypted data.

If business logic requires complex mathematical functions, then a compiled binary language might be needed. The business logic code can be on the client computer, the application server, and the database server. However, the application server is the most common location for business logic. One of the easiest ways to speed up a query is to reduce the number of logical I/Os by eliminating a table access from the execution plan. This can be done by appending to the index all columns referenced by the query. These columns are the select list columns, and any required join or sort columns.

  • This is best applied when testing the application with properly sized data for the first time.
  • There is always this pesky security team which is like, "You need to secure systems. You need to add this and that." Sometimes that adds overhead.
  • Research suggests if a website takes longer than 3 seconds to load, users leave right away and don’t come back.
  • It is good to attend conferences to keep abreast of emerging technologies or frameworks, and conferences also give you the chance to meet potential developers.
  • A sizing engineer should build in margin for application inefficiencies.
  • This dialog, performance by security, is what the rest of the company understands.

Highload is when the infrastructure needs to be urgently scaled. Highload is when one server is not enough for customer service. And on Black Friday, the store is attacked by 50 buyers at once - and their number does not decrease. According to the usual pattern, consultants walk next to each one, guard the customers at the fitting room, run after a desired size. At this rate, only 5% of those who potentially will leave the shop with purchases have a chance to be served well, and even that number can only be reached in the best case scenario.

Implementing The Application

DNS supports balancing based on Round Robin, enabling to specify multiple IP addresses of receiving web servers, called frontends. Here you need to install several identical frontends so that DNS will give different IP addresses to different clients. This way, you ensure balancing between the frontends. Once you start using several backends, requests from the same user will be sent to different servers.

How Highload Can Affect Your Applications Performance?

For these reasons, you’ll have to pay a lot of efforts for maintaining and scaling a web application, thus wasting time, costs, and energy and losing clients. Considering the development of a high-load system leaves you with doubts? Have a look at our projects and you’ll know what to do. Just click here to drop your request and share the idea to be realized. We have created the app for data collection for iOS and Android Operation System. It is perfectly suited for small-to-medium network size IoT applications.

The data entities A and B above show the containers which contain denormalized information about the Users and their Posts. Subsequently, the data entities C and D denote the different actions which users may take. The entity C denotes the event where a user likes a post and entity D denotes the action when a user follows another user. These actions are read by the related micro-services from the stream and processed accordingly. For instance, the LikeEvent can be read by the Media Counter Service and is used to update the media count in the data storage.

Most of these tools have recommendations on how to fix SQL queries. Scalability means having strategies for keeping performance good, even when load increases. In order to discuss scalability, we first need ways of describing load and performance quantitatively. We briefly looked at Twitter’s home timelines as an example of describing load, and response time percentiles as a way of measuring performance. In a scalable system, you can add processing capacity in order to remain reliable under high load.

Android and iOS mobile app with automated payments, add geolocation services, integrate local market stakeholders, and as a result - the product for rapid grocery delivery in 15 minutes? What are the key issues to developing an e-learning product? We develop, implement and customize the IT architecture. According to the metrics, it is selected or developed from scratch, fully or in parts. Elements and interaction techniques are selected in correspondence with the future load and the required level of reliability.

The Internet: Bgp Security

From the engineering perspective, a lack of resources causes performance degradation. But I cannot agree with the definition because it does not count software for the systems which cannot scale at all. Since The Social Network movie was released, I wanted to develop such kind of software. Business grows, the more you’re going to need advanced IT solutions. Get a free consultation from our experts on the implementation of your project.

Queueing delays often account for a large part of the response time at high percentiles. Even if those subsequent requests are fast to process on the server, the client will see a slow overall response time due to the time waiting for the prior request to complete. Due to this effect, it is important to measure response times on the client side. Our first response is usually to add redundancy to the individual hardware components in order to reduce the failure rate of the system. Disks may be set up in a RAID configuration, servers may have dual power supplies and hot-swappable CPUs, and datacenters may have batteries and diesel generators for backup power. When one component dies, the redundant component can take its place while the broken component is replaced.

Let’s discuss these factors one by one so you can make a better decision when building your next scalable high-performance website. Maintainability has many facets, but in essence it’s about making life better for the engineering and operations teams who need to work with the system. Good abstractions can help reduce complexity and make the system easier to modify and adapt for new use cases. Good operability means having good visibility into the system’s health, and having effective ways of managing it.

Scalability can be assessed through the ratio of the increase in system performance to the rise in resources used. Also, scalability means the ability to add extra resources while keeping the structure of the central node intact. To one extent or another, most of them experience such issues. However, the degree of their complexity depends on how well the web applications were designed from the very beginning.


Whatever your project size is, in some instances, you may be required to scale up. This is the cloning of essential elements of a system. For example, a company can redistribute its solution to more servers if it expects a surge in load. This is done even if one server is still managing all traffic. On the other hand, some use high-load architecture to allow for the possibility of scaling up when demand grows. The architecture was initially developed to handle a number of up to 10,000 active users simultaneously.


Some examples are AppDynamics, Stackify Retrace, and New Relic AMP. This is the time spent on sending data from one tracked process to another. This is calculated per each process that happens in your app and then aggregated into a single execution. Make sure that your expectations of scaling justify the expenses.

Backend is responsible for the dynamic processes on the page and data storage management, which makes it more prone to bottlenecks. The backend can be built with any multifunctional programming language like Javascript, Python, Ruby, C#, etc. The frontend is an abstraction that provides a user interface. For example, open a new tab of the browser, type the address of some website, and press Enter.

A well-designed page template is understandable, and the visual component is impressive, simple and easy to navigate. The website scalability definition is the ability of a system, network, or process to cope with the increase in workload when adding resources . To better understand the underlying principles and highlight the advantages of this approach, we will cover various related concepts, types of application architecture, and popular frameworks. They support our in house development team on various complex web projects.


However, certain core transactions required by users can require selective denormalization for performance purposes. This is mandatory for today's Internet applications where trade is conducted 24 hours a day. However, corporate systems that run in a single time zone might be able to tolerate after-hours downtime. You can use this after-hours downtime to run batch processes or to perform system administration. In this case, it might be more economic not to run a fully-available system. The distance between users influences how the application is engineered to cope with network latencies.

This may lead to the conclusion that optimization efforts should be directed elsewhere (such as transport protocol optimizations, specialized hardware, and client-side caching). Enterprise systems most commonly implement A/P fault tolerance and recovery through fault transparency by diverting services to the passive system and bringing it on-line as soon as possible. Robotics and life-critical systems may implement probabilistic, linear model, fault hiding, and optimization control systems instead.

The main advantage of the proxy when it comes to scaling is multiple server requests coordination. It enables service performance increase due to the nodes adding. The load balancer will distribute the loads according to the criteria that have been set up.

We utilize over 30 various software development technologies and commit to keep up with the latest software development market trends.
