Load Balancing for Applications and Technologies

Applications play a bigger role than ever in driving today’s modern businesses. Reliance on these as well as new cloud, virtualization and mobile technologies along with a more distributed workforce create boundless opportunities as well as unique challenges. IT is expected to serve as a broker to deliver these services and applications on-demand to enable agility while also ensuring that the following requirements are met.

  • application availability
  • flexible scalability
  • performance visibility
  • secure access

KEMP’s LoadMaster load balancers support a wide array of web and productivity applications from leading technology vendors including Microsoft, VMware, Oracle and IBM. Additionally, LoadMaster also provides high availability and traffic acceleration for custom .Net applications and web services built on IIS, Apache and other web platforms. This combined with the ability to deploy LoadMaster as a virtual machine, dedicated hardware appliance, public cloud ADC or bare metal software instance provides the greatest level of flexibility.

Load Balancing in Azure with LoadMaster

The Microsoft Azure Infrastructure as a Service (IaaS) platform enables applications to be easily provisioned in Microsoft’s cloud. Existing on premise applications can be seamlessly transitioned into Azure, allowing technology decision makers to benefit from the scalability, elasticity and shift of capital expenses to operational ones. When Microsoft Azure is incorporated into an organization’s hybrid cloud strategy, many exciting benefits are realized!

Microsoft Exchange Servers in Amazon Web Services (AWS) - A Use Case

Amazon Web Services (AWS) is Amazon’s Cloud infrastructure platform. It delivers similar tools and services to those available from Microsoft Azure. One of the central services offered in AWS is Amazon EC2; this is Amazon’s method of providing scalable virtual servers on demand from an Elastic Cloud, hence the name EC2. It’s simple and cost effective to deploy however many server instances required via the EC2 web interface. These servers can run any of the popular operating systems in use today.

Load Balancer settings when migrating from Exchange Server 2010 to Exchange Server 2013

The load balancer setup plays a vital role in client connection to Exchange Server. It helps establish the connection from the client to the Exchange Client Access Server (CAS) servers, which runs the client connection service, and distributes the client connection load across the multiple backend Exchange servers. Load balancers have various mechanism to check the health and availability of target CAS servers and establishes the connection to the most suitable one at any given time.

Load Balancer settings when migrating from Exchange Server 2013 to Exchange Server 2016

When performing this migration both versions of Exchange Server will need to coexist on the network. To do this Microsoft Exchange Server 2013 must be running Cumulative Update 10 (CU10) or later. If you have not updated your Exchange Server 2013 infrastructure to CU 10 then you must do this before introducing Exchange Server 2016 if you want them to work together.

Load Balancing NGINX

NGINX is a high performance webserver designed to handle thousands of simultaneous requests and has become one of the most deployed web server platforms on the Internet. KEMP LoadMaster can bring resilience and scalability to your NGINIX environment with an easily deployable load balancer that can service millions of active connections in a highly available configuration.

Load Balancing WordPress on NGNIX

NGINX is a high performance webserver designed to handle thousands of simultaneous requests and has become one of the most deployed web server platforms on the Internet and is especially suited to delivering workloads such as WordPress.

A load balancer can maintain the availability and performance of WordPress on NGNIX by ensuring that requests are evenly spread across NGNIX servers, that NGNIX host failures are handled gracefully without end user impact and that user traffic is optimized to reduce load on the NGNIX WordPress servers.

SSL Offload for NGNIX

NGINX is a high performance webserver designed to handle thousands of simultaneous requests and has become one of the most deployed web server platforms on the Internet. A key component of delivering applications and services with NGNIX is the use of SSL to secure the communications between clients and the NGNIX servers.

Single Sign-On for NGINX

NGINX is a high performance webserver designed to handle thousands of simultaneous requests and has become one of the most deployed web server platforms on the Internet. KEMP LoadMaster can provide Single Sign-On across multiple applications including those hosted on NGNIX. LoadMaster offers a number of authentication options including Active Directory, Kerberos Constrained Delegation (KCS), LDAP, RADIUS and SAML and provides a single point of control for user access to applications. Two factor authentication schemes are also supported.
