Rehosting involves migrating existing on-premise applications to the cloud with minimal changes. This is often the quickest method, moving your applications to a cloud provider like AWS without altering their architecture. It’s suitable for organizations seeking to move quickly and with minimal disruptions.

Replatforming (Lift, Tinker, and Shift)

In this strategy, businesses make slight optimizations to their applications while migrating them to the cloud. These tweaks improve performance without drastically changing the application’s core architecture. Replatforming offers a balance between speed and enhanced functionality.

Refactoring (Rearchitecting)

Refactoring is a more complex migration process in which applications are rebuilt to take full advantage of cloud-native features. This method is ideal for businesses seeking scalability, flexibility, and improved performance but requires a longer timeline and more resources.

Repurchasing

This involves switching from on-premise applications to cloud-based solutions, such as moving from a licensed software to a Software as a Service (SaaS) offering. It’s a popular choice for businesses replacing outdated systems with modern cloud-native tools.

Retiring

During migration, some legacy applications may no longer be needed. These applications can be retired to simplify the environment and reduce maintenance costs.

Retaining (Revisiting)

For some applications that are not cloud-compatible or need further evaluation, businesses may temporarily retain them in their on-premise environments and revisit their migration later.

Planning the Migration

Proper planning is critical for a successful on-prem to cloud migration. The following steps outline the necessary preparations to ensure a smooth transition:

Insights from Experts

Gain expert insights into the benefits and challenges of on-premise to cloud migration.

1. Trave Harmon CEO at Triton Technologies

Q1. What are the key benefits of migrating from on-premise infrastructure to the cloud for businesses?

Primary benefit: significant reduction in physical infrastructure and hardware maintenance. It is all handled by the cloud provider reducing the purchase and/or utilization of redundant systems that are needed in house.

Secondary benefit: near instant upgrades for when you begin to utilize and consume all your resources. Servers can take days or weeks to be acquired by the manufacturer, while in most cloud providers it’s in minutes for deployment.

Tertiary benefit: geo-distributed infrastructure. Since your infrastructure no longer lives locally, you can have people all over the world access, control and utilize the system with very little headache locally. Your headquarters are no longer a requirement to store and access all of this information when it can be distributed through multiple data centers throughout the United States.

Q2. During the on-premise to cloud migration process, what are the most common challenges that organizations encounter? Are there any specific technical, operational, or security-related hurdles that you have come across?

Most of the issues we have encountered when migrating have been about perception. When you go to buy a server, you get something that you think you’re going to need for a long time. You look 3 to 5 years out and purchase accordingly. A vast majority of those servers and never maximized therefore resulting in waste in purchasing. While in cloud it is encouraged to utilize 90 to 95% of your server before having the upgrade. So you can start small with the cloud and step up later having near 100% investment return instead of having it waste in a closet somewhere. With cloud your able to chop up functions and performance with greater control. Do you need a hard drive with nearly 5000 Iops? To do so on in Prem would require significant hardware investment, downtime and tweaking. That can take weeks if not months. With Amazon cloud, right mouse click, change iops, apply. Five seconds. If it is not improving performance you can go back, while hardware investment you cannot. As for security is actually been very good because Amazon has a dedicated staff to help businesses be compliant and for them to disclose security and how it is met at their facilities.

Q3. Based on your experience, what strategies or best practices can businesses employ to overcome these challenges effectively? Are there any methodologies, or approaches that you recommend for a smoother transition?

The biggest selling point for cloud for us is, do you want to work from everywhere and do you want the hardware to be someone else’s problem? That has been a massive selling point for a lot of our clients because they don’t have to do upfront massive investments in infrastructure that may fail on them at any time. They will be resistant to environmental concerns, outages and so forth.

2. Nikita Sherbina CEO & Co-Founder at AIScreen

1. Personally, in my software company, we experienced a significant increase in productivity after migrating from on-premise to the cloud. The cloud infrastructure provided our employees with easier access to resources, improved collaboration, and the ability to work remotely, resulting in enhanced efficiency and faster project delivery.
2. During our on-premise to cloud migration, we faced a specific security-related hurdle. We had to ensure the protection of sensitive customer data during the transfer process. By implementing strong encryption measures, conducting thorough security audits, and working closely with our cloud service provider, we successfully addressed this challenge and maintained the integrity of our data throughout the migration.

3. Sudhir Prakash Senior Director, Quality Engineering at Ping Identity

1. Migrating from on-premise infrastructure to the cloud offers several key benefits for businesses. Firstly, it provides scalability and flexibility, allowing businesses to easily adjust their resources based on demand. Secondly, it can lead to cost savings, as businesses only pay for the resources they use and can reduce spending on hardware and maintenance. Thirdly, it enables remote access, making it easier for teams to collaborate from anywhere.
2. During the migration process, organizations often encounter challenges related to data transfer, application compatibility, and security. Data transfer can be time-consuming and complex, especially for large volumes of data. Ensuring that applications function correctly in the cloud can also be challenging. Security is another major concern, as businesses need to protect sensitive data during and after the migration.

To overcome these challenges, I recommend thorough planning and testing. Businesses should conduct a comprehensive assessment of their current infrastructure, identify potential issues, and develop a detailed migration plan. They should also test the migration process on a small scale before fully transitioning to the cloud.

In terms of methodologies, the lift and shift approach can be a good starting point for businesses new to cloud migration. This involves moving applications to the cloud without any modification, which can be quicker and less risky. However, for long-term efficiency and cost-effectiveness, businesses may need to consider re-architecting their applications to fully leverage cloud capabilities.

Lastly, partnering with a trusted cloud service provider or consulting with a cloud migration expert can be invaluable in navigating the migration process and ensuring a smooth transition.

Q1. What are the key benefits of migrating from on-premise infrastructure to the cloud for businesses?

As businesses grow, scaling up on-prem infrastructure takes time. Capacity planning, ordering the right kind of hardware, getting it setup in the datacenter and provisioning it for its business purpose can take 1-3 months, including significant time-efforts from the operations teams. Scaling up in the cloud is much easier, faster, cheaper and easier to predict (in terms of cost increases & storage+compute capacity). * Maintaining on-prem infrastructure hardware, upgrading systems, security, monitoring requires dedicated Ops teams, some with specialized training, leading to significant costs for the business. A lot of these costs can be streamlined by using by moving to the cloud. The cloud provider takes care of maintenance, security, system upgrades, etc.

Most businesses interacting with your company will require that your systems comply with GRC standards, SSAE16/18 SOC standards, etc. This is a must have for your businesses which handle sensitive data like user data. This can be quite complex and expensive for the business to achieve on on-prem hardware. Major cloud providers will provide this compliance out-of-the-box, letting companies focus on their business.

System load (Service QPS, compute needs, etc.) for businesses vary significantly by time of day and day of week. Scaling down is not possible with on-prem systems. On migrating to cloud, we were able to dynamically scale our resources up and down based on demand.

As an ad-tech company, we had big-data more than 10 years ago before modern cloud providers and cloud data platforms existed. We had to build our own data platforms with on-prem hardware for storage and compute. Significant cost goes into maintaining the data platform, updating the platform with new technologies over time (Spark, kafka, flink, etc.), upgrading platform technologies over time, building integrations with new data platforms (Snowflake is still new), etc. Moving to cloud offloads all of these things to the provider and allows engineers to focus on building ETL, AI/ML pipelines while getting access to the latest technologies as the cloud platforms make it available. Most cloud providers now provide the latest and greatest in AI/ML integrations out of the box, e.g. OpenAI integration / AI CoPilot on Azure Cloud.

Q2. During the on-premise to cloud migration process, what are the most common challenges that organizations encounter? Are there any specific technical, operational, or security-related hurdles that you have come across?

There can be a significant cost to move legacy on-prem systems for established businesses. Most of the legacy systems were not built with cloud in mind. These systems may have monolithic, non-containerized applications that run on secure on-prem infrastructure. It will take significant planning and long efforts (many months to years) from multiple ops teams, engineering teams, compliance teams, etc. to successfully migrate and see full benefits of cloud migration.

Operationally, the Ops teams (SysOps, TechOps, Cyber-Security, etc.) have to be re-trained on the new cloud-specific practices, paradigms & technologies which are significantly different from on-prem operation practices, paradigms and tech.

High QPS systems like ones in ad-tech are highly sensitive to network latency. The ad-tech system is also highly distributed with hundreds of different applications (some applications have thousands of instances running at a time to handle load) communicating with each other. These applications are hosted and run close to each other to ensure low-latency and reliable communication. Migrating to the cloud for a business of this size is a piece-meal effort and applications are migrated in phases. Connectivity across components being moved incrementally to the cloud is difficult due to latency and network issues affecting QoS. For ad-tech, this high latency is very visible to users browsing the internet and disruptive to business. https://www.thinkwithgoogle.com/consumer-insights/consumer-trends/mobile-site-load-time-statistics/

In the process of migration from on-prem to cloud, you are either sending data between on-prem and cloud on the open internet which creates potential for security issues and latency or have to buy for express routes / direct connections which can be very expensive for businesses with large data flows (like AdTech)

Q3. Based on your experience, what strategies or best practices can businesses employ to overcome these challenges effectively? Are there any methodologies, or approaches that you recommend for a smoother transition?

Moving from on-prem to cloud has advantages but is costly and time consuming. Businesses should strictly evaluate whether they need to migrate all their systems to the cloud or only part of the system. Cloud is not a silver bullet. Migrating off on-prem to the cloud may not be ideal for parts of the business that are not meant to grow and do not have high costs, e.g. old systems maintained for legacy reasons. New greenfield projects can be planned to be cloud native from the start.

Some businesses treat cloud migration as an engineering led project. Migration from on-prem to the cloud should be a business-led decision and be conducted with a coherent cloud strategy. Engineering and operations then need to build an execution plan, starting with migration of the least critical systems, then the more failure-tolerant systems and finally the most mission-critical, business sensitive systems. There are lessons for the business and individual teams along the course of the migration and businesses should adjust their plans based on these.

Cloud providers provide a myriad of service options for similar purposes, e.g. Almost every cloud provides cold storage, warm storage, slow cache, low-latency fast cache. It is important to test and figure out which solution suits your application’s needs before building business systems around it. I have seen engineering teams building applications around the wrong technology based on spec sheets and assumptions, only to realize that the cloud technology does not satisfy QPS / latency / availability / etc. requirements.

9. Martijn van Nieuwenhoven Owner at The Code Connectors

With my background in machine learning, AI and software design, I’ve been part of many companies’ cloud migrations. From experience, it’s a lot like moving homes. You decide what to take, toss, and how to transport everything – businesses face similar choices about digital assets. It can get complex, creating challenges.

Big issues are cost overruns, legacy system compatibility, data security, and database struggles. In one project, mid-migration we found a client’s legacy platforms weren’t fully compatible with the new cloud system. Major wake-up call about thorough planning and due diligence!

To tackle these, I advise the 6 Rs of migration: rehosting, re-platforming, re-purchasing, refactoring, retiring, and revisiting. The strategy depends on unique needs, budget and timeline.

For one company, we chose re-platforming. They had strong existing infrastructure but needed flexibility and scalability impossible on-premise. Re-platforming leveraged what worked while integrating cloud benefits.

Done right, the payoffs are huge – reduced costs, better performance, top-notch user experiences, increased scalability. I’ve seen firsthand the transformation, with major improvements to the bottom line.

While daunting, with detailed planning, the right strategy, and experienced help, companies can harness the cloud’s power to drive growth and profit.

Migrating from on-site to the cloud is a complex shift – but just like moving homes, take it step-by-step and the rewards can be tremendous. The cloud’s potential is vast, but getting there requires forethought and care.

You now have the ability to speed up or slow down according to the market’s bends and curves. You can quickly scale up or down to respond to fluctuating demand, much faster than a traditional on-premise setup would allow.

I remember a project where we were helping a mid-sized retail company migrate their on-premise inventory management system to the cloud. The transformation was dramatic. Processes that once took hours, were whittled down to minutes. Their IT team, previously consumed by maintenance chores, could now focus on innovating and adding real business value. However, it’s important to note that the path to these benefits is not always a smooth ride.

Organizations often face a myriad of challenges during this migration journey. To name a few, there can be technical hiccups, like compatibility issues with legacy systems. Operational challenges can spring up, such as the need to retrain staff to effectively operate in the cloud environment. And then, there are security considerations. My stint as a security analyst has made me acutely aware of the importance of fortifying cloud architecture against potential threats. It’s essential to ensure a company’s digital assets are as secure in the cloud as they were within the on-premise firewall.

During one of our migration projects, we came across a significant security challenge. The client had a series of proprietary algorithms they used for market analysis. Naturally, they were concerned about securing these valuable assets in the cloud. To tackle this, we had to devise a custom encryption solution that would keep their algorithms safe while still being functional in the new environment.

To overcome these challenges, organizations can employ various strategies. A successful migration is not just a lift-and-shift operation but requires meticulous planning, thorough discovery, and assessment, followed by the actual execution. It reminds me of a chess game, where every move is crucial and impacts the outcome.

For the technical side, best practices include re-factoring or re-platforming applications for cloud compatibility. On the operational front, businesses can invest in staff training and create cross-functional teams for a smoother transition. For security, a comprehensive strategy that includes encryption, identity and access management, and regular audits is essential.

From a broader perspective, it is important to ensure alignment between the cloud strategy and overall business objectives. A business case for cloud migration must be established that includes the expected return on investment and an analysis of the value to be gained.

Having been through numerous migrations, I’ve found that a phased approach often works best. This involves migrating a small, non-critical application first, learning from that experience, and then gradually moving to more complex systems.

Despite the challenges, the long-term advantages of cloud migration are too compelling to ignore. The process of transitioning to the cloud is a significant undertaking, but with a well-thought-out strategy, it can lead to a rewarding destination.

So there you have it, the dance of cloud migration in all its challenging but rewarding glory. It’s a dance I’ve been a part of many times over, and I’ll continue to be a part of it as technology keeps evolving. If you need more specific insights or perhaps another anecdote from my experiences, don’t hesitate to ask.

Q1. What are the key benefits of migrating from on-premise infrastructure to the cloud for businesses?

The key benefits include the security, scalability, and convenience that a Cloud-hosted infrastructure provides. You are gaining the security tools and insights that a major provider like Azure offers, with OpEx vs CapEx pricing and fast scalability for servers and applications, and the convenience of offloading your infrastructure maintenance to a CSP vs an IT staff that may be overworked or under-resourced to stay current.

Q2. During the on-premise to cloud migration process, what are the most common challenges that organizations encounter? Are there any specific technical, operational, or security-related hurdles that you have come across?

Most common challenges involve re-pointing or upgrading legacy applications to reference the new Cloud infrastructure, with a similar correlation for users who are used to the way we’ve always connected. However, a well-planned Cloud migration will consider what can be shifted, what must be upgraded, and incorporate end-user training into the project.

Q3. Based on your experience, what strategies or best practices can businesses employ to overcome these challenges effectively? Are there any methodologies, or approaches that you recommend for a smoother transition?

The best thing a business can do is align themselves with an experienced and trusted CSP for their migration project. These efforts are more than just lift-and-shift a few VMs and often involve updating user authentication methods, a review of licensing, upgrading applications, and user training needs. A true CSP partner will be able to provide a comprehensive project plan laying out the scope, costs, and risks for your organization.

Q1. What are the key benefits of migrating from on-premise infrastructure to the cloud for businesses?

Due to the variety of projects and technologies chosen by on premise solutions, there isn’t a single answer that works for all teams trying to migrate to the cloud. However, in general the most common use cases for shifting to the cloud are around modernization of security, access to the newest features of the cloud and shifting cost by adopting a scale-to-zero or scale-to-infinity model. For example, in older applications routing and middleware were handled at the application level; modern solutions allow using API Gateways and computes that auto-scale, automatically handle JWT validation and handle protection against DDoS or other malicious attacks. The modern cloud features are also continuously improved to protect against new vulnerabilities, shifting the full burden from the app dev team.

Q2. Based on your experience, what strategies or best practices can businesses employ to overcome these challenges effectively? Are there any methodologies, or approaches that you recommend for a smoother transition?

In addition to the technical work, migration to the cloud requires a team transformation. This is one of the biggest hurdles that teams will face. With distributed architectures, the underlying technology is handled by different teams working for different organizations. This means the process in gaining access and modifying permissions needs to change. Basically, support and maintenance practices need to be adjusted.

Effecting this change is tricky, so teams should aim to leverage as much automation as possible to reduce the burden of responsibility involved in the migration process. Our experience with migrations is creating technology to automate the process of deploying infrastructure. Deploying infrastructure is usually performed by the infrastructure team when migrating to the cloud, and it has an extremely steep learning curve. It can ultimately be a blocker for other teams, such as the app developers. By automating this complexity, operations teams can instead spend their time designing a pathway into the cloud which works for their specific organization. It also means the developers are not blocked and can continue to run their migrations in parallel.

1. Migrating to the cloud has multiple benefits, from transferring certain responsibilities to the cloud provider, such as physical security, availability and redundance, hardware maintenance and upgrades to other benefits that make your organization more efficient and agile such as: elastic compute (only use the compute when you need it, no need to over provision for burst of usage), quicker scalability and services that make the management of the infrastructure easier such as orchestration services and platform as a service offerings, and, last but not least, better carbon footprint since cloud providers minimize their carbon footprint.

2. The migration to the cloud has to be carefully planned to ensure that the organization will not open any vulnerabilities and that it will take the most advantage of the cloud offerings. One of the biggest mistakes that I see is a simple lift and shift where organizations grab their existing infrastructure and move it to the cloud as VMs; while this works and removes some of the responsibilities from the business, it usually is more costly than running their on-premise services and there are no tangible improvements. Instead, the migration should take into account each of the components that are moving to the cloud and see if there is a cloud offering that can replace the legacy service, not only saving the organization infrastructure cost but also many hours of maintenance in the long run. While running in the cloud can be very secure (we run all our infrastructure in the cloud at Keytos), as I showed in my Defcon talk Cloud defaults are easy, not secure, the cloud is designed to be easy to use, but it has to be locked down and a proper security analysis must be done before deploying your infrastructure to the cloud to avoid any errors that might be overlook when moving from a closed on-premise infrastructure to a cloud that can be accessed from anywhere in the world.

Conclusion

Migrating from on-premise to the cloud unlocks significant benefits like cost savings, scalability, and enhanced security. By adopting a strategic approach, businesses can ensure a smooth transition.
