Why Consider Cloud Migration for Your Business?

Migrating to the cloud, especially when coupled with DevOps workflows, offers numerous advantages. It is more cost-efficient in terms of operational expenses (OPEX), requires no upfront capital expenditure (CAPEX), enhances security, scalability, and operational resilience, accelerates time-to-market for products and features, and presents a plethora of other business benefits compared to on-premises or dedicated servers. However, the effectiveness of this approach in achieving business goals hinges on the correct design, implementation, and configuration of your cloud strategy and DevOps methodology, which can be a challenging task.
Key Considerations for Cloud Transformation Strategy

When formulating a viable cloud transformation strategy, businesses must address several crucial questions. While the specifics may vary depending on the business domain and project requirements, certain points remain universally relevant:

• Should the application be lifted and shifted to the cloud, or is it more beneficial to rebuild it from scratch?
• Which components of the existing infrastructure and workflows will be migrated to the cloud?
• What elements must be replaced with cloud-based tools and services?
• What data processing approach will be adopted? Will it involve a public, private, hybrid, or multi-cloud strategy?
• How will data migration to the cloud be executed, if at all?
• Should advanced cloud features like Big Data analytics be implemented immediately or planned for proactively?
• Most importantly, who will handle the cloud migration and ongoing infrastructure management?

Despite the enticing benefits of cloud migration, businesses must exercise caution due to the substantial investment required. It is imperative to thoroughly comprehend all alternatives and anticipate the outcomes of addressing the aforementioned questions before proceeding with cloud migration endeavors.


Regarding Application Architecture:
Many legacy codebases and applications, typically developed 5-10 years ago, are monolithic in nature and struggle to efficiently handle heavy workloads. Typically, they attempt to manage peak loads by requesting additional RAM memory and CPU power, which is both inefficient and costly. This challenge is commonly addressed by transitioning to a microservices architecture. By breaking down the application into smaller, independent components, each part can scale autonomously, ensuring system resilience, cost efficiency, and fault tolerance.
In some cases, applications can be seamlessly migrated to the cloud through a lift-and-shift approach without significant refactoring. However, others may rely on outdated technologies lacking cloud-compatible equivalents, necessitating a rebuild using cloud-native technologies and RESTful APIs. Consequently, business stakeholders must make informed decisions based on project requirements and budget constraints regarding whether to pursue a lift-and-shift migration or opt for a cloud-native rebuild.

Regarding IT Infrastructure Components:
Every business evolves uniquely, constructing its IT infrastructure based on available budget, technology, and expertise. Over time, many of these investments become outdated or inefficient, evolving into legacy systems. In such instances, migrating these systems to the cloud is often inefficient. Instead, it's advisable to discard them before embarking on cloud migration and replace their functionality with relevant cloud-based services and tools.

Regarding Data Storage and Processing:
The public cloud emerges as the most economical option, offering adequate security and scalability when appropriately configured. This involves deploying auto-scaling groups behind a Content Delivery Network (CDN) to facilitate scalability, along with implementing a bastion host to safeguard private subnets for database security. However, regulatory requirements may necessitate the use of a private cloud, particularly in cases where customer data must remain within national borders, such as medical or financial applications. In such scenarios, a portion of the public cloud infrastructure can be isolated and provided exclusively for use, albeit at an additional cost. This ensures data storage within a designated Availability Zone, guaranteeing compliance with territorial regulations.

Hybrid Cloud and Multi-Cloud Strategies:
The hybrid cloud model proves advantageous when specific data must be securely stored and rapidly processed on-premises, while other system components reside in the public cloud. This configuration is particularly beneficial for applications involving Big Data processing, training Machine Learning models, and conducting prescriptive analytics.
Alternatively, the multi-cloud strategy involves spanning systems across multiple cloud platforms and utilizing services from various cloud vendors. This approach is beneficial for high-workload projects requiring a combination of services from different providers to fulfill specific functionality requirements. It fosters cloud-agnostic modular infrastructures, facilitating the seamless swapping of components as needed.

Regarding Data Migration:
Every business handles diverse types of data, and virtually every application relies on some form of database. Depending on the chosen approach to cloud migration—whether it's a lift-and-shift or a cloud-native rebuilding—the need may arise to upgrade database versions or migrate to a different database altogether. This decision ranks among the most critical aspects of the project.

Regarding Implementation of Latest Features:
Cloud migration presents an opportune moment to future-proof your application. During this process, you can replace outdated databases with more robust alternatives boasting enhanced features. By decomposing monolithic architectures into microservices and integrating RESTful APIs, you can enhance application performance and streamline integration with third-party products. Moreover, you can proactively plan for the implementation of cutting-edge technologies such as Big Data analytics, serverless computing functions, blockchain, AR/VR, and others. Integrating these features as part of your cloud transformation strategy eliminates the need for subsequent investments. However, if time and budget constraints are a concern, this task can be deferred or deemed irrelevant, depending on the nature of your application.

Regarding Contractor Selection:
Choosing the right contractor for your project is a critical decision that can significantly impact its success. You have several options to consider:

• Tasking your in-house IT team with the cloud transition and allowing them to learn through trial and error.
• Attempting to attract the necessary talent through hiring, which entails investing an unspecified amount of time and money in recruitment and HR management to build a cohesive team.
• Delegating the task to the support engineers of Amazon Web Services or Google Cloud Platform, which carries the risk of vendor lock-in.
• Hiring a dedicated team from an IT outsourcing company, which entails the risk of entrusting the project to an unscrupulous contractor.

While each option has its drawbacks, the disadvantages of working with an IT outsourcing company can be mitigated relatively easily. Conducting background research and seeking feedback from previous customers can help alleviate concerns. A reputable Managed Services Provider like ITProvider.io will boast numerous positive customer reviews, be recognized in various ratings, and offer references from satisfied clients.

Constructing Hyper-Converged Cloud Infrastructure for Your Projects
Hyper-Converged Cloud Infrastructure (HCI) refers to a virtualized environment where all configurations are scripted rather than performed manually. This aligns precisely with the Infrastructure as Code (IaC) approach, a DevOps best practice as previously discussed. At ITProvider.io, we utilize tools such as Terraform and Kubernetes, which utilize "manifests"—textual files containing comprehensive descriptions of environment characteristics and settings in a straightforward language. These manifests can be versioned like any other code, facilitating the effortless deployment of specific environment versions by simply launching the corresponding manifest.
By employing this approach, both software delivery for new product features and cloud infrastructure management tasks become highly repeatable, transparent, and predictable. Utilizing manifests eliminates the potential for human error and ensures the consistency of environments—from the developer's Integrated Development Environment (IDE) to production—thus resolving the long-standing "works on my machine" dilemma. At ITProvider.io, we leverage Terraform and Kubernetes to construct immutable and high-performing cloud infrastructures across various cloud vendors, including Amazon Web Services, Google Cloud Platform, Microsoft Azure, DigitalOcean, and others.
