Best practises for E2E Cloud migration

August 5, 2022

Are you planning to migrate to E2E cloud services? Then you must know how to do it precisely and efficiently. So, if you are not aware of this process, then you have landed on the right page. Here, you will find the necessary guidance on completing this process without any hassle.

So, read on.

Choose a migrating strategy

When you are migrating your services to E2E, then there are three options for you – 

  1. A fresh installation of the app/web service in the new location
  2. Migrating offline by cloning the existing servers
  3. Working with a migration expert to do a live, hot migration

Choice 1: Fresh Installation

Remember, these are not the precise steps, but the precise steps will depend on your app. But here are some general things you need to do before migrating your services or apps:

  1. Make a catalogue of your existing apps.
  2. Review the backups of your apps or web services as your worst-case scenario plan.
  3. Deploy the new cloud servers of E2E of the suitable speed, size, speed, and OS.
  4. Install your apps to the E2E servers.
  5. Try migrating the data and all these config files to the E2E servers.
  6. Redirect to E2E servers' DNS and URLs.
  7. Remove all the data from the old servers.

Choice 2: Image Backup and Restore

Before you use this method, we warn you it is not suitable for most customers. If you are not an expert system administrator (or sys admin for short), don’t use this step because there are many low-level config settings to be performed. You need to also check whether the server meets the E2E requirements.

Here are the following steps for backing up with images and restoration:

  1. Make a backup of the server files and your app/web apps resources
  2. Cleaning the server
  3. Server image file export with the help of Virtual or Physical servers
  4. Testing with QEMU
  5. Raw format conversion
  6. Stage the image at the E2E server
  7. Add the image as an E2E snapshot
  8. Deploy the server from a snapshot
  9. If required, expand the file system
  10. Re-install cloud-init (initialization command)

Choice 3: Use a Migration Partner

If you are using a migration partner, then you will have to do live migration. If your apps cannot stand the migration downtime, it is highly recommendable to hire a hybrid cloud management expert who knows live migrations in and out. The expert should be well versed in cloud backup and should know how to recover from a crash. You can hire the services of companies like Rackware and Siatik, which specialise in cloud migration.

Steps for Choice 1: Fresh Installation

Step 1: Make a catalogue of your existing apps

After locating the web server’s config settings, search for the virtual host config files, SSL certificates, DB connection settings, and app control files for a freshly-deployed E2E server.

Step 2: Review the backups of your apps or web services as your worst-case scenario plan

Store all data in a local server where you can access these files in offline mode. If you have any other online server backup service, then it is better to store it there as the transfer is quite easy.  

Step 3: Deploy the new cloud servers of E2E of the suitable speed, size, speed, and OS

Deploy equal-sized infrastructure for every existing web services/app component, such as block storage, compute instances, load-balancers or managed databases. To choose a location and to run a speed test, use commands like mtr, ping, or traceroute for testing the routing, latency and bandwidth between your location and the location of the data centre.

For example – here is a test execution of our server location from Delhi.

# mtr

You should check the power of the server, storage capacity and managed services that are equal to your old environment. You should check whether your OS is Linux or Windows.

Step 4: Install your apps to the E2E servers

Use configuration management tools like Packer, Terraform, Ansible or Puppet for installing the same stacks on the E2E servers.

Step 5: Try migrating the data and all these config files to the E2E servers

Use tools like FTP, scp, rsync, third-party migration tools, or GUI migration tools to migrate your data to the E2E servers. After that, you have to test your app or web service thoroughly to see whether everything is in order. You need to check the performance with load tests and functional tests before redirecting the traffic.

Step 6: Redirect to E2E servers' DNS and URLs

You might want to lower the hop limit or TTL (time to live). Keep it at 5 minutes a few days before you start redirecting the traffic. Most DNS servers have a TTL of 24 hours. This will ensure the quick modification of the DNS of new E2E servers. 

Step 7: Remove all the data from the old servers

Remove all the data of the old servers after thoroughly checking any unwanted activity or logging in on the old server. Free the old server after a careful check. 

Steps for Choice 2: Image Backup and Restore

Make a backup of the server files and your app/web apps resources. Also, ensure your device has ample free disk space for converting the disk images to their raw format.

Step 1: Make a backup of all files

Make a backup of all the files and how you will access them in case of any issues. 

Step 2: Cleaning the server

If you want to clean the server for free disk space then here is how you can do it:

# zerofree -v /dev/sda2

# dd if=/dev/zero of=/tmpfile bs=4096k; rm -f /tmpfile 

Server image file export with the help of Virtual or Physical servers

If your hosting machine is capable of this, then skip this set. Otherwise, you can either export the image with the help of a premise virtual server like QEMU, Microsoft Hyper-V or VMWare. If you want to do it through a physical server, then you can use a dd server. Export the with the command given below:

# dd if=/dev/sda bs=1M of=/mnt/USB_external/server_image.img

Step 3: Testing with QEMU

This is optional. It helps to check whether the Virtual Input/Output drivers have been installed properly or not. 

Step 4: Raw format conversion

E2E allows conversion into images with free utilities like QEMU or VirtualBox. You can do it by executing the two commands given below.

$ qemu-img convert -f vmdk -O raw image.vmdk image.img

$ VBoxManage clonemedium disk /path/to/image.vdi image.img --format raw

Step 5: Stage image at E2E server

Stage this converted image into an E2E server using scp or rsync. The commands for doing these are given below: 

$ scp -C image.img root@

$ rsync -z --progress image.img root@

Step 6: Check the image on the given URL of the LAMP server

Step 7: Add image as E2E snapshot

In your customer portal, upload the image by browsing the given menu, Products > Snapshots > Add Snapshot. 

Step 8: Deploy server from a snapshot

You can check the method for this over the internet or on the blog post we have written for it. Ensure that VPS SSD is of an equal size.

Step 9: If required, expand the file system

Confirm the accuracy of the disk, partition, and filesystem sizes using the following commands. 

  • Verify the disk size: fdisk -l
  • Verify the partition size: parted -l
  • Check the filesystem size: df -h

The command given below helps in resizing the file system

$ sudo resize2fs /dev/vda1

Step 10: Re-install cloud init

Does the server have cloud-init installed beforehand? Remove all the configuration files and cloud-init files completely. After that, reinstall cloud-init. The E2E server should start receiving new vendor information from the Metadata API.

To sum up, the precision of this migration will largely base on the server OS and app’s infrastructure. E2E is responsible for the platform infrastructure but not the app’s infrastructure and previous cloud server dynamics. Moreover, you are responsible for the administration of your app’s development until and unless they are specifically services managed by E2E and E2E Kubernetes engine or databases managed by E2E. So, keep these in mind while going ahead with the migration process.

Comparison between Cloud-Based and On Premises GPUs

Cloud GPUs vs On Premises GPUs

Cloud GPUs are typically more powerful than on-premises GPU instances. The cost of renting a cloud GPU is generally lower than the cost of purchasing an on-premise GPU. 

Cloud platforms offer fast access to high performance compute and deep learning algorithms, which makes it simpler to start using machine learning models and get early insights into your data. 

Cloud GPUs are better for machine learning because they have lower latency, which is important because the time it takes a neural network to learn from data affects its accuracy. Furthermore, cloud GPUs allow users to take advantage of large-scale training datasets without having to build and maintain their own infrastructure.

On Premises GPUs are better for machine learning if you need high performance or require access to cutting-edge technologies not available in the public cloud. For example, on-premises hardware can be used for deep learning applications that require high memory bandwidth and low latency.

Cloud GPUs: Cloud GPUs are remote data centers where you can rent unused GPU resources. This allows you to run your models on a massive scale, without having to install and manage a local machine learning cluster.

Lower TCO: Cloud GPUs require no upfront investment, making them ideal for companies that are looking to reduce their overall capital expenses. Furthermore, the cost of maintenance and upgrades is also low since it takes place in the cloud rather than on-premises.

Scalability & Flexibility: With cloud-based GPU resources, businesses can scale up or down as needed without any penalty. This ensures that they have the resources they need when demand spikes but also saves them money when there is little or no demand for those resources at all times.

Enhanced Capacity Planning Capabilities: Cloud GPU platforms allow businesses to better plan for future demands by providing estimates of how much processing power will be required in the next 12 months and beyond based on past data points such as workloads run and successes achieved with similar models/algorithms etc... 

Security & Compliance : Since cloud GPUs reside in a remote datacenter separate from your business' core systems, you are ensured peace of mind when it comes to security and compliance matters (eigenvector scanning / firewalls / SELinux etc...) 

Reduced Total Cost Of Ownership (TCO) over time due to pay-as-you-go pricing model which allows you only spend what you actually use vs traditional software licensing models where significant upfront investments are made.

Cloud GPUs: Cloud GPUs offer significant performance benefits over on-premises GPUs. They are accessible from anywhere, and you don't need to own or manage the hardware. This makes them a great choice for data scientists who work with multiple data sets across different platforms.

Numerous Platforms Available for Use: The wide variety of available platforms (Windows, Linux) means that you can run your models using the most popular machine learning libraries and frameworks across different platforms without having to worry about compatibility issues between them.

Impact of the Strong Dollar: Cloud Costs Increasing, Be Indian Buy Indian

Indian SMEs and startups are feeling the effects of the high dollar. These businesses use hyperscalers(MNC Cloud) who cannot modify their rates to account for the changing exchange rate. For certain companies, even a little shift in the currency rate may have a significant effect on their bottom line. Did you know, when the INR-USD exchange rate moved from 60 to 70 in December 2015, it had an impact of around 20% on Digital Innovation?

As the rupee is inching closer to 82 per dollar, the strong dollar has directly impacted the costs of cloud services for Indian businesses. The high cost of storage and computing power, along with bandwidth charges from overseas vendors, has led to a huge increase in the effective rate of these services. This is especially true for startups and SMEs that rely on cloud computing to store and process user data. With the strong dollar continuing to impact the cost of cloud services, it is essential for Indian companies to evaluate their options and adopt local alternatives wherever possible. This blog post will discuss how the strong dollar impacts cloud costs, as well as potential Indian alternatives you can explore in response to this global economic trend. 

What is a Strong Dollar?

A strong US dollar($) is a term used to describe a situation where a US’s currency has appreciated in value compared to other major currencies. This can be due to a variety of factors, including interest rate changes, a country’s current account deficit, and investor sentiment. When a currency appreciates, it means that it is worth more. A strong dollar makes imports more expensive, while making exports cheaper. Strong dollars have been a growing trend in the past couple of years. As the US Federal Reserve continues to hike interest rates, the dollar strengthens further. The rising value of the dollar means that the cost of cloud services, especially from hyperscalers based in the US, will rise as well. 

Increase in Cloud Costs Due to Strong Dollar

Cloud services are essential for modern businesses, as they provide easy access to software, storage, and computing resources. Cloud services are delivered over the internet and are typically charged on a per-use basis. This makes them incredibly convenient for businesses, as they can pay for only the resources they actually use. Cloud computing allows businesses to scale their resources up or down, depending on their current business needs. This makes it suitable for startups, where demand is uncertain, or large enterprises with global operations. Cloud computing is also inherently scalable and allows businesses to quickly react to changing business needs. Cloud computing is a very competitive industry and providers offer attractive prices to attract customers. However, these prices have been impacted by the strong dollar. The dollar has strengthened by 15-20% against the Indian rupee in the last few years. As a result, the costs of services such as storage and bandwidth have increased for Indian companies. Vendors charge their Indian customers in Indian rupees, taking into account the exchange rate. This has resulted in a significant rise in the costs of these services for Indian companies.

Why are Cloud Services Becoming More Expensive?

Cloud services are priced in US dollars. When the dollar is strong, the effective price of services will be higher in Indian rupees, as the cost is not re-adjusted. There are a couple of reasons for this price discrepancy. First, Indian customers will have to pay the same prices as American customers, despite a weaker Indian rupee. Second, vendors have to ensure that they make a profit.

Possible Indian Alternatives to Cloud Services

If you're looking for a cost-effective substitute for services provided by the U.S.-based suppliers, consider E2E Cloud, an Indian cloud service provider. When it comes to cloud services, E2E Cloud provides everything that startups and SMEs could possibly need.

The table below lists some of these services and compares their cost against their US equivalents. 

According to the data in the table above, Indian E2E Cloud Services are much cheaper than their American equivalents. The difference in price between some of these options is substantial. When compared to the prices charged by suppliers in the United States, E2E Cloud's bandwidth costs are surprisingly low. Although not all E2E Cloud services will be noticeably less expensive. Using Indian services, however, has an additional, crucial perk: data sovereignty.


The price of cloud services will rise as the US Dollar appreciates. Indian businesses will need to find ways to counteract the strong dollar's impact on their bottom lines. To do this, one must use E2E Cloud. The availability of E2E Cloud services in INR currency is a bonus on top of the already substantial cost savings. An effective protection against the negative effects of a strong dollar.

Actions CEOs can take to get the value in Cloud Computing

It is not a new thing to say that a major transition is on the way. The transition in which businesses will rely heavily on cloud infrastructure rather than having their own physical IT structure. All of this is due to the cost savings and increased productivity that cloud technology brings to these businesses. Each technological advancement comes with a certain level of risk. Which must be handled carefully in order to ensure the long-term viability of the technology and the benefits it provides.

And CEOs are the primary motivators and decision-makers in any major shift or technological migration in the organization. In the twenty-first century, which is a data-driven century, it is up to the company's leader to decide what and how his/her organization will perform, overcome the risk and succeed in the coming days.

In this blog, we are going to address a few of the actions that CEOs can take to get value in cloud Computing.

  1. A Coordinated Effort

As the saying goes, the more you avoid the risk, the closer it gets. So, if CEOs and their management teams have yet to take an active part or give the necessary attention that their migration journey to the cloud requires, now is the best time to start top-team support for the cloud enablement required to expedite digital strategy, digitalization of the organization, 

The CEO's position is critical because no one else can mediate between the many stakeholders involved, including the CIO, CTO, CFO, chief human-resources officer (CHRO), chief information security officer (CISO), and business-unit leaders.

The move to cloud computing is a collective-action challenge, requiring a coordinated effort throughout an organization's leadership staff. In other words, it's a question of orchestration, and only CEOs can wield the baton. To accelerate the transition to the cloud, CEOs should ask their CIO and CTO what assistance they require to guide the business on the path.

     2. Enhancing business interactions 

To achieve the speed and agility that cloud platforms offer, regular engagement is required between IT managers and their counterparts in business units and functions, particularly those who control products and competence areas. CEOs must encourage company executives to choose qualified decision-makers to serve as product owners for each business capability.

  1. Be Agile

If your organization wants to benefit from the cloud, your IT department, if it isn't already, must become more agile. This entails more than simply transitioning development teams to agile product models. Agile IT also entails bringing agility to your IT infrastructure and operations by transitioning infrastructure and security teams from reactive, "ticket-driven" operations to proactive models in which scrum teams create application programme interfaces (APIs) that service businesses and developers can consume.

  1. Recruiting new employees 

CIOs and CTOs are currently in the lead due to their outstanding efforts in the aftermath of the epidemic. The CEOs must ensure that these executives maintain their momentum while they conduct the cloud transformation. 

Also, Cloud technology necessitates the hire of a highly skilled team of engineers, who are few in number but extremely expensive. As a result, it is envisaged that the CHRO's normal hiring procedures will need to be adjusted in order to attract the proper expertise. Company CEOs may facilitate this by appropriate involvement since this will be critical in deciding the success of the cloud transition.

  1. Model of Business Sustainability 

Funding is a critical component of shifting to the cloud. You will be creating various changes in your sector, from changing the way you now do business to utilizing new infrastructure. As a result, you'll have to spend on infrastructure, tools, and technologies. As CEO, you must develop a business strategy that ensures that every investment provides a satisfactory return on investment for your company. Then, evaluate your investments in order to optimise business development and value.

  1. Taking risks into consideration 

Risk is inherent in all aspects of corporate technology. Companies must be aware of the risks associated with cloud adoption in order to reduce security, resilience, and compliance problems. This includes, among other things, engaging in comprehensive talks about the appropriate procedures for matching risk appetite with technological environment decisions. Getting the business to take the correct risk tone will necessitate special attention from the CEO.

It's easy to allow concerns about security, resilience, and compliance to stall a cloud operation. Instead of allowing risks to derail progress, CEOs should insist on a realistic risk appetite that represents the company plan, while situating cloud computing risks within the context of current on-premises computing risks and demanding choices for risk mitigation in the cloud.


In conclusion, the benefits of cloud computing may be obtained through a high-level approach. A smooth collaboration between the CEO, CIO, and CTO may transform a digital transformation journey into a profitable avenue for the company.

CEOs must consider long-term cloud computing strategy and ensure that the organization is provided with the funding and resources for cloud adoption. The right communication is critical in cloud migration: employees should get these communications from C-suite executives in order to build confidence and guarantee adherence to governance requirements. Simply installing the cloud will not provide value for a company. Higher-level executives (particularly the CEO) must take the lead in the digital transformation path.
