Load balancing: Why do you need it?

From scaling suddenly during peak traffic periods to evenly distributing user load among servers, load balancing is essential to successful IT management. But what is load balancing, and why is it necessary? This blog post looks at the load balancing process and its various benefits, including improved reliability, scalability, and enhanced security. We’ll also cover the technical considerations and automated solutions that help organizations make the most of this powerful technology. Read on to learn more about why it is necessary and how it can help your business succeed in today’s digital environment.

What is Load Balancing, and why is it necessary? 

Load balancing is a process of distributing workloads across multiple servers to balance computing power and provide increased reliability, scalability, and availability in an IT environment. This is accomplished by introducing a load balancer – a dedicated device or service. It watch the traffic in your cluster and direct the flow of requests accordingly. By distributing the workload across multiple servers, it’s possible to achieve higher throughput and performance, as well as maximize resource utilization.

Load balancing is essential for any organization with a large or complex IT environment. By balancing the load in a network or system, you can ensure that resources are efficiently allocated and that each of your users experiences an optimal performance. This helps minimize potential service outages and reduce server congestion, ultimately leading to higher customer satisfaction. Additionally, it can significantly improve the scalability of your IT services by allowing you to add additional computing power when needed quickly.

Outline of Load Balancing Process

The load balancing process involves diverting or redirecting traffic among the various servers in a network. First, the load balancer will analyze the user requests and determine which server is best suited to accommodate the request. This is done by considering various factors such as CPU utilization, memory usage, and the number of current requests the server is handling. Depending on the load balancer being used, the algorithms may exploit additional factors. An example is the calculation of latency, client IP address, or the user’s geographic location.

Once the appropriate server has been determined, the load balancer will forward the user request to the server. The server will handle the request, process the result, and inform the load balancer. The load balancer will then respond to the user with the requested information. This process continues each time a user requests a page or resource, ensuring that all requests are distributed evenly and equally and that the most suitable server is always used.

Benefits of Implementing it

Load balancing offers several benefits, including improved reliability and scalability. By distributing the workload among multiple servers, these services can remain online much more often, as any single point of failure will not bring down the entire system. Additionally, it helps to ensure that your application is not excessively overloaded. It reduces wait times for your users and improving performance.

Additionally, load balancing allows for increased scalability. By using a load balancer, your IT environment can quickly respond to sudden demand by automatically increasing or decreasing resources as needed. This allows for dynamic and flexible scaling. And allow your organization to provide additional computing power without needing to make system changes or incur high costs. This scalability can be further optimized in the cloud, as it gives access to a rapid-scale environment as required.

Automated Load Balancing Solutions 

Automated load balancing solutions can provide increased scalability and efficiency. How? By allowing organizations to quickly and efficiently respond to changing demand levels. These solutions are often offered as a cloud-based service, allowing for rapid and dynamic scaling of resources. This can not only help prevent short-term service outages but also reduce costs by avoiding over-provisioning computing power. Automated load balancers also provide additional security benefits by implementing firewalls, proxies, and SSL encryption algorithms and access control measures.

Conclusion

Load balancing is an essential tool for successful IT management, providing increased scalability, reliability, and availability of services. By incorporating automated load balancers into your IT stack, you can quickly and efficiently respond to sudden changes in demand. At the same time, they are improving performance levels and providing enhanced security. Investing in the proper load balancing solution can help businesses remain competitive in today’s digital landscape and maximize their return on investment.

GeoDNS: How to start using it?

So you want to start using GeoDNS. Congrats! That means your business is growing or already big.

Step 0. Know what GeoDNS is?

A Geographical Domain Name System or GeoDNS is a method to distribute the traffic considering the location where the DNS query was generated. GeoDNS involves a network of name servers located in strategic points of the planet. These servers have different IP addresses for the same domain based on the region or area they cover, and that represents an incredible speed boost for the DNS resolution.

The trick of GeoDNS is that it redirects the traffic based on the DNS clients’ IP addresses.

How to start using GeoDNS?

Step 1. Check your needs

Consider the real needs of your business. Analyze if you need such a network of multiple servers worldwide working for you. What’s your market? Do you have an international company or a very local one? GeoDNS is a great option for most businesses because it brings many benefits, like speed, efficient traffic distribution, IP filtering, quicker loading time, constant uptime, and redundancy!

But mostly, international companies use it because they receive a high volume of DNS queries 24/7 from clients around the world. Since the queries are produced in very different and far away locations, deploying GeoDNS makes total sense.

Step 2. Research DNS providers

Research different GeoDNS providers. Look for a quality and trustable service. And check that the locations it offers (network) are convenient to cover your specific market needs.

Step 3. Analyze the DNS plans

Analyze the different available plans of that provider. Don’t pay more for extras you don’t need. Calculate the number of DNS queries you expect to be sure the plan will cover your needs. Read carefully all the policies for payment, contract cancellation, technical support, the fine print, etc., not to be surprised.

Step 4. Configure your network

Once you get the service, your provider will run the GeoDNS, but you have to configure it on your system. You just need to add an IP address to every server in the world you choose to be close to your clients. It is easy. Just be careful while typing the IP addresses.

Step 5. Test

Run a test. Usually, the interface of most providers includes a tool to test (like Ping) what you configure and the changes you make. Test that the servers respond to the IP address you added to them.

Step 6. Your system is ready to start using GeoDNS

Wondering what will happen next? Well, when a user sends a DNS query to visit your domain, the DNS resolution process will be triggered, but this time, GeoDNS will make a big difference. The DNS server will read the IP address of the users to get their locations. Then, their queries will be sent to the nearest server to be processed. The answer to them will be quick, and the loading time will be reduced considerably.

Conclusion

GeoDNS is a great technology! If your company is steadily growing, already international, or if it is on the way to reaching that level, start using it today and enjoy its multiple benefits.

DNS outage – Everything you need to know

Imagine you have been preparing for months for the special sale of your e-shop. Clients impatiently wait for the countdown to point out the beginning. And when they all try to access your website, your domain name can’t be loaded. Clients receive an error message on every try. Yes, pretty sure your e-shop is experiencing a DNS outage.

And the issue is that this can make your clients angry or disappointed. You will lose money, and your reputation can be affected.

Better be prepared and know more about DNS outages. Here you have everything you need to know. Including how to prevent them!

What’s a DNS outage?

DNS outage or DNS downtime, as it’s also called, is a time interval during which a domain name can’t be resolved to its IP address.

The Domain Name System (DNS) and its resolution process are essential for accessing any domain name. If there’s a failure causing the DNS not to work, the necessary translation from domain name to IP address won’t happen. So the domain won’t be located, and therefore, its content won’t be accessible to visitors.

What causes a DNS outage?

A DNS outage can happen due to different causes:

  • Human errors. Yes, humans are behind a large number of DNS outages. For example, a script error, a misconfiguration, or a single typo on the IP address of the domain name can cause a DNS failure.
  • DDoS attacks. If the traffic overloads sent by attackers make your DNS servers crash, the domain name will be down.
  • Lack of redundancy. Of course, you can run your domain name with only an authoritative server, but it can be risky. Software or hardware failures, updates, regular maintenance, or a cyber attack can shut it down.
  • Propagation delays. Online businesses must delete, edit, or add different DNS records regularly. Propagating these modifications or updates across a complete network can take time. Technically, this is not an error or a cause of a DNS outage, but visitors who can’t reach your domain will perceive it like that. Once the DNS propagation gets completed, everything will be ok.

How to prevent a DNS outage?

Look for redundancy

Redundancy is key! You can use Secondary DNS services. Using multiple Secondary DNS servers, you can set them as Secondary authoritative nameservers. In case the Primary gets attacked or suffers downtime, the Secondary servers will answer the DNS requests of your clients.

Use DNS failover

This technology can automatically redirect traffic to a different server. In case of a server’s failure, DNS failover will get activated for the DNS resolution process to keep going. So your website will be accessible even if a server falls.

DNS load balancing

Load balancing is a great practice to avoid a DNS outage. While distributing traffic through the available servers, it can handle traffic spikes and prevent servers from being overloaded.

Conclusion

Preventing DNS outages on your online business is possible! Take action now! Don’t let it stop your operation.

Benefits of using a Monitoring service

Precisely what does a Monitoring service entail?

Monitoring services are a broad category of goods that enable analysts to check whether IT equipment is online and operating as expected, as well as to address any issues they may uncover. It offers comprehensive information about the condition of your servers, which you use for a number of services, including web, email, DNS, and others. Many Monitoring service plans and options are available, ranging from thorough inspections to advanced tools that can evaluate a product’s performance in great detail and even automate repairs when defects are found. Actually, so-called Monitoring Checks are used to do this. There are many different kinds, and every company offers a selection. TCP monitoring, DNS monitoring, and other popular ones are among the most well-known and frequently used ones. However, many others are also advantageous. So let’s look at the popular ones of them now.

Types of Monitoring service checks

There are various ways to analyze a service’s uptime or downtime. In addition, you are informed if a check is unsuccessful. Here are a few examples of the most typical check types:

  • ICMP Ping Monitoring check

This check offers details on network activity involving a specific domain or IP address. The system tests an IP address using the ICMP ping protocol.

  • TCP Monitoring check

Using the provided IP address (IPv4 or IPv6) and port number in the Transmission Control Protocol, the system establishes a Transmission Control Protocol (TCP) connection.

  • UDP Monitoring check

The computer verifies the precise IP address to the User Datagram Protocol (UDP) port number you or your system administrator specified.

  • DNS Monitoring check

The hostname that you or your administrator provided is checked in DNS by the system. You can also select the query type for the specified IP address.

Benefits of using it

You should employ a Monitoring service for a number of good reasons.

  1. Unwanted power outages can be avoided.

You might be able to identify and prevent a number of problems that lead to downtime and DNS outages with the help of a monitoring system. It is a straightforward technique. When you have up-to-date information, you can react very rapidly.

  1. You can now see more of your network.

The Monitoring service increases visibility by displaying real-time network performance data, issuing alerts via email and text, and presenting it in an understandable manner.

  1. Better security

Sometimes downtime is caused by fraudulent attacks like DDoS (Distributed Denial of Service) attacks and DoS (Denial of Service), not network issues. Monitored providers will catch any unwelcome infections and keep your organization secure, whether there is an effort to infiltrate an enterprise network or a raging part of spyware is trying to sneak in.

Conclusion

Huge congrats! You’re getting closer to using the Monitoring service. Why? Because you understand its objective, advantages, and various check types. So, what happens next? To put it into action. Good luck!
