Recently, there was an instance where over 200,000 people had to wait to access the lottery housing subscription website and it caused quite a stir in South Korea. Without an ADC (Application Delivery Controller), the sudden surge in traffic flows could have led to service paralysis and widespread confusion. 

Application Delivery Controller(ADC) is a network appliance that enhances application performance and availability through traffic management and optimization. ADC is an advanced form of load balancer, offering not only basic load distribution but also advanced features such as caching, compression, and encryption/decryption. ADC reduces the server loads and shortens application response time.

PIOLINK's ADC (PAS-K), which ranks No.1 in the Korean ADC market, has been recognized for its excellent performance across various sectors such as finance, public services and education. It resolves traffic overload directed at the servers and ensures uninterrupted and stable application delivery services to users. Its high availability, performance and scalability make it ideal for on-premises and cloud infrastructure environments.

PIOLINK's newly released models 'PAS-K11000 and PAS-K12000' are high-performance ADC(L4·L7) capable of handling large-scale traffic of 100 Gbps and 200 Gbps. They resolve bottlenecks and handle large-scale traffic stably, providing users with a more comfortable service experience. Additionally, with the support if ultra-fast 100 GbE ports, high-performance network construction is possible. There are virtual models as well. As virtual ADC appliances ,PAS-K11000V and PAS-K12000V allow for 56 and 72 virtual ADCs to be used respectively on a single device.

They receive requests from the client and forward them to the appropriate server, using techniques such as load balancing and traffic management to ensure that requests are distributed evenly across servers and that the servers are operating efficiently. In the event of a server failure, it ensures continuous service by automatically redirecting users to another server. If unexpected issues like earthquakes or fires occur at one site, the response time path is calculated to connect to an appropriate site among the remaining ones, ensuring uninterrupted service operation.
