Cloud Migration | How can Parallels Remote Application Server help?

cloud migrationThe world is experiencing a significant shift to cloud migration. Over the years, the cloud has evolved as the epitome of agility, flexibility, and scalability. About 90% of companies are on the cloud today, and experts state that 60% of workloads are running on a hosted cloud service. As more organizations reap the benefits of shifting their applications and data to the cloud, others might find it to be a challenging deal.

What is Cloud Migration?

The cloud refers to servers located in data centers all over the world and accessed over the internet. These servers store data and run applications such as databases and CRM software, so end-users and other companies do not have to manage their own database and software applications.

The Cloud Migration Deployment Models

Cloud migration refers to the process of moving applications, data, and other components to a cloud-based structure. There are multiple cloud migration models which might include:

The public cloud is the most common model.

Benefits of Cloud Migration

If done right, cloud migration can benefit organizations tremendously by ensuring lower upfront costs, scalability, and expansion to new geographical locations. The benefits of migration are:

Improved operational efficiency

Cloud migration removes region-specific dependencies, thus improving team collaboration, productivity, and efficiency. It also opens a pathway for organizations to utilize the talent pool located in different geolocations.

Improved agility

The time required for procuring new storage space in on-premises solutions is large but can be reduced to a matter of hours because of cloud migration. This improves system agility in this rapidly evolving technological world.

Extra functionalities

Cloud packages offer additional features like continuous deployment, monitoring, automatic logging, and disaster recovery over traditional, existing organizational services.

Robust security

Cloud solutions usually have security programs with security features like analytics and visibility of the cloud environment. A migration can improve security in comparison to on-premises solutions.

Decreased costs

Deploying data and applications in the cloud is comparatively cheaper to bare-metal deployments. Pay-as-you-go models additionally offer flexibility to counter seasonal demands. With a migration, you can also scale up or down your storage easily, without procuring new servers and keeping them idle for long periods, hence keeping costs under control.


Cloud solutions offer promises of close to zero downtime, and the support provided by these solutions ensure improved resource availability. This eventually leads to customer satisfaction and better asset utilization.

Automatic Updates

Cloud services roll out server updates regularly, thus making it easier to deploy server updates and feature updates with ease at the customer end. Eventually, customers get faster deployment facilities after cloud migration.

Reduced footprint

Cloud migration ensures a reduction in the number of data centers required by the company, eventually leading to a reduced organizational footprint.

The Challenges of Cloud Migration

Cloud migrations may be tricky. The following are some of the main obstacles that many businesses are confronting when they move their resources to the cloud.

Insufficient Planning

Many businesses begin their cloud migration without giving it the time and consideration it needs. Thorough end-to-end cloud computing strategy is necessary for successful cloud migration and execution. Each software and dataset might just have unique needs and constraints, necessitating the use of a particular cloud migration strategy. For each task that is moved to the cloud by the company, a solid business case needs to be made.

Security of Data and Compliance

Data security and compliance are two main barriers to cloud migration. A shared responsibility approach is used by cloud services; they are in charge of protecting the infrastructure, while the client is in charge of protecting data and applications. Therefore, even if the cloud provider could offer strong security measures, it should be the duty of your firm to set them up properly and make sure that all operations and apps have the proper security controls.

Vendor Lock-In

Vendor lock-in is indeed a problem that cloud technology users frequently encounter. Although cloud service providers provide a wide range of services, many of them are not compatible with other cloud platforms. It takes time and money to move operations from one cloud towards another. When they first begin using cloud services, many firms find it challenging to transfer providers if the present one doesn’t meet their needs.

Cost Management

Many businesses that migrate to the cloud do not have clear KPIs in place to determine how much money they will spend or save following the move. This makes it challenging to determine whether migration was beneficial economically. As new services are accepted and application demand increases, cloud environments are also dynamic and pricing can vary quickly.

How can you efficiently migrate to the cloud?

Develop a Cloud Migration Strategy

A cloud migration strategy should be based on Gartner’s 5R strategy. The 5R strategy is a starting point that helps decide the best migration strategy suited for your purpose. The 5R strategies are:






Decide which applications to migrate and which to keep native

Some applications of a system make sense in-house while some are suited for cloud migration. Some applications have special needs inside an organization and may contain features required for internal processes. On the other hand, some applications need to be shifted to the cloud for easier administrative advantages, disaster recovery, faster deployment, and reduction of geographic dependencies.

Hence, it makes sense to analyze the entirety of the system and only start the migration after taking the proper decision about native and cloud-suited applications.

Create a cloud migration checklist

Before you get started with the migration, it makes sense to create a migration checklist that includes:

Choosing the appropriate platform

The first step in the cloud migration process is to decide the amount of exact storage and overhead storage needed. This helps organizations choose the best hosting option and pricing.

Choosing the licensing model

Cloud licensing models are based on virtual processor counts and the ability to scale application services and servers. Hence, another checklist in the cloud migration process is to choose the correct licensing model that adds business value to the organization.

Checking network traffic needs

When deploying applications and data on-premises, the existing network devices can employ hardware acceleration to take care of heavy traffic. However, virtual routers and switches on the cloud might not be able to meet traffic needs. Hence, it is important to check current traffic needs before starting cloud migration.

Reviewing Access Control List (ACL) Dependencies

ACLs regulate user and service activities, and cloud migration can affect ACL dependencies. When shifting to the cloud, organizations must ensure that the new model meets the current ACL dependencies.

Auditing IP Addresses

Old DHCP static addresses and scope will likely change after cloud migration. Auditing existing IP addresses ensures that dependent sockets are not broken down after the migration.

Auditing SSLs and Certificates

Changing the existing host location to the cloud’s host location can throw SSLs off track. Hence, it is also important to audit SSLs and certificates so that they can be replaced or reviewed after cloud migration.

Prepare for audit

Before starting a migration, organizations must plan and prep in advance, to make complying with audits simpler. Once the migration is complete, all traffic interactions must be analyzed and logged as any string of data can have great business implications.

Analyzing the raw data can be intimidating and tiresome at first. It is therefore important to prepare for an audit by using the best log analysis solutions that can assist with compliance in the long term.

Keep compliance in mind

It is also necessary to keep compliance in mind after a migration. When in the cloud environment, it is important to run root cause analysis and trace logs to stop malicious activities from affecting the cloud environment. To ensure compliance, organizations must choose a service that has:

Logging services

The interaction between virtual and physical machines must be compiled, recorded, and saved in highly secure locations.


The data saved in the secure location must be immutable with heavy encryption.

Data retention policies

The period for retaining data in the cloud ranges from 3 to 12 months. It is hence important to define and implement proper data retention policies for compliance.
