Cloud Implementation Strategy For Legacy Apps

The last decade has witnessed a tremendous growth in Cloud Migration. Today, Cloud Computing has become one of the most disruptive phases in modern IT and an increasing number of enterprises are adopting the trend to realize cost and scale efficiencies. But, CIOs and other technology leaders face numerous challenges while developing a cloud implementation strategy for their organization in order to meet their business goals.

In this article, we will discuss a Cloud Implementation strategy for legacy applications focusing on the common benefits and challenges of these migration processes.

Assess Individual Application Requirements

Before moving a legacy application to the cloud, it is important to assess the requirements of individual applications taking users and organizational needs into consideration. As the migration process is largely invisible to the users, moving a client-server application to the cloud without assessing the outcomes carefully can lead to higher angst among users. This will affect the productivity and can put future application migrations at risk.

Consider the Application Architecture

Move your traditional applications to cloud only if you see an obvious benefit. Cloud offers operationalized economics, improved simplicity and instant scalability but simply moving a traditional client-server based ERP infrastructure to cloud – as a lift-and-shift operation – without taking appropriate connectivity decisions can have disastrous consequences for users. Most database applications handle network latency poorly and shifting just the server side of a client-server application to the cloud will often increase latency beyond tolerable levels. Also, these types of applications were designed with private data centers in mind and rebuilding so much surrounding infrastructure in the cloud can often negate the financial and simplicity benefits.

Decide a Migration Process

Moving your legacy apps can be done in two different ways:

  • Copying the VMs to cloud and restarting them at the provider: This yields the best outcomes when the speed of deployment is the main concern. But there may be some complexities due to the surrounding infrastructure as mentioned earlier.
  • Rebuilding the application environment from scratch: Legacy App migration is a good opportunity to clean up and ensure that the application operating environment adheres to the latest best practices. Thus, it makes sense to rebuild the application environment considering the organizational goals and budget.

Prioritize the Applications before Migrating

Before you migrate your applications to the cloud, decide the order in which you want to “make the move”. Generally, very few organizations can simply migrate all their applications at once. Thus, prioritization is critical. These suggestions will help you prioritize your applications effectively:

  1. Start with non-critical services: Starting with non-critical services will help your staff get an idea about the overall process and learn lessons that can be applied to move critical workloads. You will also learn about how your cloud service provider supports your workloads. This will help you make the required changes as you move your critical applications to the cloud.
  2. Migrate appropriate services to SaaS: For many companies these days, operating local collaboration environments isn’t effective. Moving to SaaS passes the responsibility of managing servers to the service providers and reduces costs by great extent. But, at the same time, many providers might not offer all the features which the companies are currently using. If your company is running a heavily customized environment, do a feature-by-feature analysis and decide if your company can survive after losing a particular feature. Otherwise, prefer to stay local.
    Likewise, cloud-based reporting services can be scaled to almost unlimited capacity and you won’t have to worry about scaling the local compute and storage resources. Thus, replacing your local data analysis services with cloud-based ones would prove helpful.
  3. Decide the applications that will stay local: Finally, account for those applications that need to stay local. It is important to keep the services like DNS, DHCP, and print servers for infrastructure support and one to two domain controllers for authentication purposes. Many companies prefer keeping the critical items local as a risk management strategy. However, this is starting to change with an increase in the robust and secure working environments.

One of the most critical parts of this migration process is choosing the right vendor to work with. It is important to ensure that your cloud vendor has the capabilities to manage and host your cloud enabled applications whilst helping you to control costs, SLAs and security that your business needs.

Virtual Private Cloud – A Feasible Substitute To On-Premises Computing

Virtual Private Cloud – A Feasible Substitute to On-Premises Computing:

Public Cloud has been gaining popularity and has become the most favorable deployment model for most organizations because of its cost efficiency and flexibility. It allows a huge number of users to share the computing resources provided by their service provider and pay only for the resources they actually use. Enterprises understand these benefits but many still prefer a private environment for their workloads because of security and privacy issues and Virtual Private Cloud (VPC) helps meet that demand.

VPC is a similar idea where the enterprises use a private cloud that is a small part of the public cloud instead of owning a cloud infrastructure themselves.

The reasons behind enterprises choosing VPCs are usually the complexities in building an on-premises private cloud from scratch. A private cloud may shoot up the costs due to increased management responsibilities and smaller economies of scale. Some enterprises may not even have the infrastructure required to completely build and manage a custom private cloud within their own IT department. According to Lauren E. Nelson, a principal analyst and private infrastructure-as-a-service cloud lead at Forrester Research, 82% of enterprises with 1,000 or more employees don’t have the employee strength to build a private cloud server.

In some cases, it is because many enterprises that think are operating a private cloud are actually just running a standard virtualized environment.


Before an enterprise chooses to deploy a VPC, it should first understand how it differs from the on-premises private cloud and the benefits and trade-offs it brings with it.

  1. Server Setup: A virtual private cloud has a lesser number of users who have higher control over their sections of the cloud server whereas, a private cloud distributes resources across multiple physical servers.
  2. Location: Generally, a VPC is hosted at an off-site which is usually hosted by a third party service provider. On the other hand, an on-premises private cloud is situated at your own data center.
  3. Cost: A Virtual Private Cloud is vastly inexpensive and cheaper as compared to the On-Premises Private Cloud. This is basically because of the costs incurred on hardware, installation, set-up and maintenance.


Essential benefits of Virtual Private Clouds:

  1. Security: The data storage, network, and hardware can be designed according to the security needs of your business and cannot be accessed by clients or companies in the same building or data center.
  2. Compliance: Since the network and storage configuration is based around your business, it is easier to monitor the security and compliance needs of your business.
  3. Customization: You can completely customize the network, storage and hardware performance according to the needs of your business. You can add CPUs, RAM, and Storage as and when required.
  4. Cost Effectiveness: The amount of money spent on Virtual Private Cloud depends on the resources required by your business. You’ll know how much each resource costs and how much you have to pay for any additional storage, hardware or network components you require.


With the many benefits of Virtual Private Clouds, enterprises these days have started taking a path towards Hybrid Cloud and are implementing VPCs to combine cloud and on-premises computing. This way, they can make use of shared resources by keeping their workloads private and secure.

Top 5 Ways Financial Services Are Leveraging Cloud Technology

The cloud isn’t quite popular in the financial sector, as it is in other industries. The financial sector deals with highly sensitive and valuable data and because of certain misconceptions about the cloud being unsecure in nature, IT leaders have been very skeptical in adopting cloud technology. But, things are changing and the financial industry is beginning to realize the improvements in operations offered by the cloud. Thus, many IT decision makers in the industry have started to “make the move”. But, there’s one simple question that pops-up when it comes to adopting the cloud – What are banks and insurance companies using the cloud for?


In this article, we have discussed the top 5 ways financial sector can leverage cloud:

Back-office systems: Hosting back-office systems in the cloud eliminates the need to deal with hardware procurement and maintenance, power and cooling, and staff utilization for regular maintenance activities. Although back-office systems are critical for any financial organization, it is an easy way to test the working of the cloud without feeling like a customer-facing system being put to risk. HR / Payroll / Time Tracking Applications, CRM, Office 365 and Digital workloads (website, email, etc.) are some of the most common applications being moved to the cloud.


Customer-facing applications: With the constant rise in customer portals and mobile applications, banks and insurance companies have been migrating their customer-facing applications to the cloud. Using the cloud reduces the need to worry about scalability and agility as compared to using the in-house management which is expensive and faces challenges in accommodating traffic fluctuations.


Policy-management systems: The insurance companies have started accepting cloud as the practical solution to host their insurance policy management systems. These hold critical customer information like policies, new claims, background checks, etc. And, since the supporting infrastructure needs to be compliant to store such information, HIPAA and PCI-compliant clouds are an ideal choice for insurance organizations.


Uptime and Disaster Recovery (DR): The use of customer portals and mobile applications also demand the banks and other financial organizations to be online and in service 24×7. The legacy disaster recovery solutions are not only slow and expensive but also hardware intensive for modern day financial institutions. By adopting cloud DR solutions, financial institutions can follow compliance requirements and reduce downtime at a fraction of the cost of their legacy DR solutions.


Business Intelligence and Analytics: Digitalization of banking processes has led to the generation of massive amounts of customer data. Companies know that this data can be mined to get meaningful insights in real-time and has to be stored somewhere. The cloud enables data storage in HIPAA and PCI-compliant manner and ensures that the sensitive information collected by banks and insurance companies is absolutely secure and available. Cloud is also scalable and eliminates the problem of quickly changing resource requirements for business analytics.


Identifying the right application, specific to the finance industry, can put a whole lot of obligations on the internal teams of an organization. Thus, working with a reputed service provider is a worthwhile solution.
