Cloud Migration: How To Have Better VPN Performance After Moving to AWS EC2

Cloud computing is quickly becoming the standard for enterprises looking to scale operations. Mission-critical workloads traditionally allocated to dedicated servers in data centers are now processed by instances running in the cloud, allowing organizations to cut down their IT expenses and eliminate upfront cost, and the complexity of integrating new technologies with existing workloads. There is no doubt that moving data and applications from on-premise data centers to the cloud is a feasible option for businesses to maintain and strengthen their competitive advantage. However, it is not always easy to make a big change to a large and established business because of all the processes, procedures, and quite recently, work arrangements.

This blog highlights particular challenges remote workers face after a migration process to the EC2 and proffers a solution to the identified issues.

What is EC2?

Elastic Compute Cloud (EC2) is an AWS service offering that allows companies to create virtual instances of their on-premise servers, store data on virtual drives, distribute loads across machines, and scale existing services.

EC2 Cloud Migration: Case Study

When considering your organization’s cloud adoption, you must take into account the people whose workflow will be affected. According to PwC, one of the biggest challenges to adopting cloud technology is the skill gap or lack of expertise. For instance, employees and users may be familiar with the old process, and it could take them significant effort to acclimate to a new system. It can also be that slight changes in operation affect other areas such as accessibility, which could be problematic as business profitability is inadvertently tied to employee’s productivity.

The case study below is a typical example of what we mean:

  • The company has three sites in the US but is looking to expand operations to the UK.
  • Data is currently being migrated to Amazon EC2 with requisite data taking the lead and legacy data hindmost (as their migration plan was devised to guarantee the least disruption).
  • Installed AWS site-to-site VPN to facilitate EC2 server access from the office.

The problem with this process is that remote users are required to use VPN to connect back to the corporate network to access files in EC2 servers as it is deployed within the Amazon Virtual Private Cloud (VPC). Consequently, the speed of access is affected, especially when the VPN has a performance issue.

Other VPN effects on remote working include:

  • VPN requires an active internet connection, a problem for employees that require on-field access to the instance or offline access to files.
  • VPN connections rely on the tunneling of public network traffic, which introduces inherent variability and unpredictability of performance.
  • CDN can’t speed up content redirected from VPN

The goal of a CDN is to serve content to users from the “closest” possible location. This allows content providers to serve content faster. However, because a VPN connects a user to a distant network, they can’t take advantage of the CDN or edge caching.

  • The office network has to be constantly monitored as any interruption could lead to a single point of failure.

Given the current economic environment, implementing a remote working policy has become essential for business. Not just to keep up with trends but also to stay ahead of the competitive market. Tackling the inefficiencies of VPN is one way to start.

How Triofox Fixes the Problem

One way management can facilitate a smooth transitioning is to mirror the existing workflow. In the case study, remote employees wouldn’t have a problem if the remote file access solution mirrored the mapped drive file access experience working within the office perimeter. Triofox can be provisioned for that.

Triofox caters to the contingent or work-from-home workforce by adding mobility and collaboration functionalities to existing file servers while providing a cloud drive letter solution for seamless operability. When used with Amazon’s EC2, it can transform the server into a private cloud file server or a private cloud file sharing solution, where authorized users can easily collaborate across regions and geographical locations. The result is that employees can stay productive on the go without management sacrificing security or convenience.

Other advantages include:

  • No need to route employee traffic through a VPN.

Triofox speeds up access to network shares without Businesses having to go through the trouble of setting up a VPN.

  • Triofox accepts file requests over HTTPS/SSL protocol and transfers (after AD authentication). It leverages the global delivery network (CDN); HTTPS-based protocol can traverse the CDN and speed up access.
  • Connection to EC2 server is independent of the on-premise network. Hence, even if there is network disruption on-site, remote workers are unaffected.
  • Speeds up access to files stored in the virtual server. Its differential upload feature ensures that only changes are synchronized, saving bandwidth and time.
  • Users can access frequently used files without an active connection to be available offline in the case of a limited or slow connection. However, files in the local cache remain encrypted at rest and can only be accessed after successful login. The files are protected with the same protection level as if they are still sitting in the cloud.
  • Provides an interface to simplify direct access to Amazon S3 buckets (when used to backup rarely accessed files in EC2 instances).
  • Employees can collaborate easily by sharing files over the Internet as secure web links. They can also access network server shares through a browser on their mobile device.
  • Remote wipe feature to deprovision compromised devices or users at the end of their contracts.
  • Provides data auditing and reporting features to keep businesses in control of what happens to their data and accountable to regulatory bodies.

Deployment Overview:

  • Install Triofox server agent on the EC2 instance (click here for the complete steps)
  • Install Triofox client agent.

For businesses yet to migrate to the cloud, Triofox simplifies the cloud migration process by integrating AD and NTFS permissions, allowing employees to maintain access to existing file shares. It can be deployed as a hybrid cloud solution, which is suitable for organizations that aren’t prepared to fully migrate to the cloud.
