Network availability refers to the operational status of a computer network and its ability to make connections, process traffic quickly, and respond to user requests.
Availability, also known as network uptime, measures how well a computer network can respond to the connectivity and performance demands placed on it. Network availability is an essential consideration in disaster planning, but it impacts life and works in so many ways. Network downtime or sluggishness equates to business downtime, at considerable cost to organizations through inefficiency, lost sales, lack of critical data for decisions, and other harmful effects.
Network availability is vital for individuals to ensure the ability to communicate with and interact with others, whether that’s a text message, a phone call, online purchase, streaming entertainment, or an emergency call. Network availability is calculated by dividing the uptime by the total time. The goal is 100% availability, although another commonly referenced goal is “five nines,” or 99.999% availability. That’s the equivalent of about two minutes of downtime in a year.
There are several ways to reach these goals, including WAN acceleration or optimization.
Network Availability is a fundamental prerequisite for access to data and applications. For enterprises that run multiple data centers, it can be a critical concern that users be able to access application servers and data everywhere with the best connections and the fastest performance.
How often have you seen a customer-facing application fail because the system is overloaded? Without a highly available network, users can’t access the data and applications they need–or can’t do so fast enough. There are a few types of denial of service. The most common is where an attacker tries to make a system or network resource unavailable to another system or network by overwhelming it with requests for that resource.
Network availability depends on several factors, including the physical location of the infrastructure devices, the amount of traffic, and how well the network is designed and maintained. For example, latency can become a significant factor in network performance when a network connects users across large geographical distances.
There are as many ways to improve your skincare regimen as there are causes of disruption. For example, because it’s essential always to access and work with your files and data, your organization may use redundant and failover systems in its network.
Load balancers are used to help ensure that requests are distributed to the resources most able to respond, and they also help prevent any individual component from being overwhelmed. The ability to quickly and efficiently scale operations up or down to meet spikes in demand is essential to a business. Scaling up or scaling down may be required to meet spikes in order, and cloud services can be used to accomplish this. Additionally, network security solutions can be used to address denial-of-service attacks.
F5 BIG-IP DNS ensures that network users and applications experience high levels of availability and performance by monitoring the status of network components and routing users to the closest or best-performing physical, virtual, or cloud environment.
You can configure your full-proxy device to monitor for DDoS attacks and protect your network from them. Big-IP DNS, available in physical or virtual appliances, is a highly scalable DNS solution that provides “always-on” availability.
