High Load Systems: What Is it and When You Need It?

Therefore, you should take one step behind and think – which part of the system causes a problem? If it’s a database, choose a high-scalable database before beginning the project development. Or you can use several databases, for instance, one for writes and one for reads (CQRS). Below, you can see some ways that will help you make high-performance scalable web applications. In addition, many cloud hosting services offer private network services, enabling software developers to safely use servers in the cloud and make the system scaling. Use the cloud to host new projects, as it allows them to reduce the cost of the server, facilitate their management, and easily deploy applications.

The most significant high-load projects, such as Google or Facebook, use hundreds of servers. They provide fast recovery after system failures and practical project expertise. Distributed systems help highly loaded applications to recover quickly if some servers go down. Software engineers at N-iX design and build robust architectures that effectively tackle common issues of the high load systems. We develop responsive and fast web applications with Python, Scala, Java, and  NodeJS.

Feature-rich and secure real estate platform

It is crucial to run independent application stacks in each of the locations, so that in case there is a failure in one location, the other can continue running. Ideally, these locations should be completely high load system architecture independent of each other. Still, when a solution scales, many architects experience added complexity to the overall architecture in terms of its manageability, performance, security, etc.

In speaking of the example with PHP, you should configure the product deployment to both the Nginx server and the PHP server, representing backend. On a typical day, a consultant approaches each client, helps to choose the size, advises accessories, then escorts to the checkout and calculates the buyer. Logically, PostgreSQL employs clusters, databases, schemas, tables, columns, indexes, views, functions, triggers, and sequences. Clusters contain databases managed by a single server, databases consist of schemas, and schemas organize database objects.

High Load Systems

A ‘hot failover’ occurs when all the servers are running simultaneously, and the load is directed entirely towards a single server at any given time. In both scenarios, tasks are automatically offloaded to a standby system component so that the process remains as seamless as possible to the end user. Failover can be managed via DNS, in an well-controlled environment.

  • Memcache will independently distribute the load between the servers by using a constant hashing algorithm.
  • It’s difficult to predict the audience size for the years to come, so it’s better to make focus on scalability.
  • Here is an example of a configuration made to organize queries balancing for appropriate backends from the particular countries of Europe.
  • For instance, when a server designed to handle only 5000 requests is suddenly getting over 10,000 requests from thousands of users at once.
  • Instagram can be a well-known example of a high-load project with a non-relational database, as it uses NoSQL.
  • Organizations who plan to fully utilize a cloud infrastructure must also be capable of meeting demands for 24/7 availability.
  • Plus, to deliver all-around software performance testing services, we focus on automation, using open-source tools for performing quick and regular testing.

Whether there are ten users in an hour or millions of users at once, the supporting infrastructure can expand to fulfill demand. Discover if your business needs a high load system in this article. Quintagroup experts create adaptive, dependable software capable of handling massive data requests and backend calculations. When developing a software system, make sure it will be able to easily withstand high loads.

You can create high availability in cloud computing by making clusters. When a group of servers work together as a single server to deliver continuous uptime, those servers are called a high availability cluster. If one server fails or is otherwise unavailable, the other servers can step in. Geo-redundancy is the only line of defense when it comes to preventing service failure in the face of catastrophic events such as natural disasters that cause system outages. Like in the case of geo-replication, multiple servers are deployed at geographical distinct sites. The locations should be globally distributed and not localized in a specific area.

Understanding PostgreSQL’s architecture is vital for maximizing its potential. A deep grasp of its inner workings empowers you to address challenges, optimize performance, and ensure data reliability. While PostgreSQL is low-maintenance, regular tasks like vacuuming, reindexing, and log management are essential. Instaclustr Managed Service for PostgreSQL offers expert management for uninterrupted application building and scaling.

Additionally, GUI mode provides debugging and the ability to look through test results. If we have a ready test plan, we use the non-GUI mode to run tests from the command line. When the load increases, a web application starts working more slowly. At some point, the reason will lie already in the implementation itself.

Twemproxy can become the solution to this situation in the form of proxy for Memcached and Redis servers. Before the start of the development process, it is necessary to choose the appropriate Database Management System. Any DBMS has its peculiarities in operation and requires at least one strong-skilled person who will manage the base.

Developing a project with a high load architecture

Even if your business is relatively small, you might notice an increase in visitors and, therefore, need to expand. So, you should take one step behind and think – which part of the system causes a problem under load? If it’s a database, choose a high-scalable one before starting the project. Or take even several databases, for example, one for writes, one for reads (CQRS).

To prevent erroneous, random, or malicious inputs that cause service outages or
security breaches, sanitize and validate input parameters for APIs and
operational tools. For example,
Apigee and Google Cloud Armor can help protect against injection attacks. But it helps me to define when we need to invest more time into optimizations and when we should avoid that. Usage of Lambda Architecture and Kafka makes the system highload. But I think that it wrongfully excludes the systems which handle fewer connections.

For more details about building highly scalable and reliable workloads using a microservices architecture, refer to Design Your Workload Service Architecture. Providing effective software testing services requires deliberate planning. During the first phase of project planning, the business analyst collects non-functional requirements against which performance metrics will be checked. Based on these requirements, we prepare a test script and one or more test scenarios. The architecture was initially developed to handle a number of up to 10,000 active users simultaneously.
