Information technology system

An information system (IS) is a collection of interrelated resources. They are used to collect, analyze, store, and distribute data and information in order to achieve a specific purpose.

Load Balancing-Load Balancing System


Benefits of using Load Balancing system:

Distribute user requests to many backends efficiently, decreasing the stress on each backend.Only deliver queries to online backends to ensure high availability and reliability. As a result, downtime is reduced when a backend fails.

Increase the overall system's flexibility by adding or removing backend at any moment.
Increase system security since backends are frequently placed in the DMZ (DeMilitary Zone - non-public area) at this time, and users connecting to the system are only connected to the load balancer rather than directly to the backend.

Current noteworthy load balancing products include: 

  • Load Balancing equipment: PEPLINK, DRAYTEK, MIROTIK,... 
  • Load Balancing-supporting firewall devices: CISCO, FORTINET, SOPHOS,... 

Next Generation Firewall – Next Generation Firewall (NGFW)

Supports common firewall capabilities such as protocol/port state checking, Network Address Translation (NAT), and virtual private network (VPN) (VPN),...

Identify and filter data based on specific apps: prevent harmful and active programmes from avoiding firewalls by using non-standard ports. An NGFW will operate as a traffic controller, monitoring transmitted and received data as well as packet content to avoid application assaults on OSI levels 4-7.

SSL and SSH Inspection: NGFW can examine SSL and SSH encrypted traffic, allowing decryption of permitted application traffic, checking other policies, and then re-encrypting the traffic. This protects the network from dangerous programmes and invasive activities by utilising encryption to evade firewalls.

The Intrusion Prevention System (IPS) performs ""deep"" traffic inspection, intrusion detection, and prevention.

Directory integration: the majority of next-generation firewalls (NGFWs) support Active Directory, LDAP, and controlled applications based on approved users and user groups.

Harmful code filtering: prevents the transmission of viruses, webpages, packets, and malicious software.

Today's excellent Next Generation Firewall products: CISCO, FORTINET, SOPHOS, JUNIPER, PALO ALTO,... reducing both upfront investment and operational expenses

SD WAN is an abbreviation for software-defined Wide Area Network. SD WAN is a virtual network architecture that allows businesses to increase their efficiency of transmission system services like LTE, MPLS, and Internet services Broadband is used to secure application connections to branches, offices, and users.

SD WAN may be used to establish WANs with comparable or superior performance by replacing part or all of WAN connectivity technology with low-cost commercial Internet access. Previously, costly private connections such as MPLS were used.

SD-Outstanding WAN's Features

Availability is really high: SD-WAN allows you greater flexibility in order to reduce network downtime. For the technology to operate, it must identify connection problems in real time and instantly switch to another connection.

Quality of Service (QoS): SD-WAN supports QoS by prioritising bandwidth for the most critical applications at the application level. To boost speed, SD WAN will dynamically route connections, deliver programmes on the faster path, or even divide applications running on both routes.

Unlike MPLS, SD-WAN uses security techniques (IPSEC) to authenticate, monitor, and encrypt the communication channel.

Administration and troubleshooting: SD-WAN employs a graphical user interface (GUI) over command-line interfaces (CLI) to assist administrators in automating route selection, setup, and central management for terminal equipment.

Load balancing: SD-WAN, which is capable of global network coverage, applies the approach of load-sharing network traffic by requesting a new route based on the current network state to deliver a better experience. The highest quality user experience.
