National Gas, the major national gas transmission network in Great Britain, has undergone a significant transformation by leveraging a scalable and flexible Microsoft Azure cloud environment. This transformation was facilitated through a strategic partnership with Capgemini, aimed at ensuring secure, cost-effective, and scalable solutions amidst a fast-approaching deadline due to their divestiture from National Grid.
Client Challenges and Objectives
Divestiture Deadline
National Gas faced an imminent challenge due to the looming deadline for its divestiture from National Grid, necessitating an urgent transition to a new cloud environment. The situation called for rapid advice, streamlined operations, and an efficient migration strategy. Traditional on-premises solutions were ruled out due to time constraints and the need for a fast, secure migration was paramount. The pressing nature of the deadline meant that any missteps could lead to operational disruptions, making it essential to adopt a robust and reliable solution that could be implemented swiftly.
Replacing legacy systems with a modern cloud-native environment required careful planning and execution to avoid any potential downtime or security breaches. It was also crucial for the new environment to be scalable and flexible enough to support future growth and innovation. Achieving these objectives within a tight timeframe presented a considerable challenge, but one that was met with a strategic approach that focused on leveraging the latest in cloud technology and automation tools.
Secure Access for Developers and Data Scientists
Ensuring secure access for developers and data scientists was a primary requirement for National Gas, as traditional laptops and on-premises solutions were not viable during the transition period. This made it necessary to find a solution that allowed for secure, remote access to the cloud environment. Developers and data scientists needed a seamless experience that would enable them to continue their work without disruption while maintaining the highest security standards.
The solution had to provide robust security measures, such as multifactor authentication (MFA) and Privileged Identity Management (PIM), to ensure that sensitive data remained protected. Additionally, the ability to monitor access and usage, as well as to implement location awareness and conditional access policies, was critical to maintaining the integrity of the cloud environment. This approach not only safeguarded against potential threats but also ensured that the right users had access to the necessary resources when needed.
Proposed Solution
Greenfield Cloud Migration
Capgemini proposed a greenfield cloud migration for National Gas, involving the creation of a new cloud-native environment from scratch. This approach was selected to guarantee that the organization could build development platforms and tools tailored to its needs while accommodating its small team and reducing operational complexity. Starting fresh with a greenfield migration allowed for a more streamlined and efficient setup, minimizing the potential for carrying over legacy issues from previous systems.
The greenfield migration approach offered several advantages, including the ability to design a cloud environment optimized for current and future needs. By leveraging Microsoft Azure, National Gas could take full advantage of the latest advancements in cloud technology, ensuring a secure, scalable, and cost-effective solution. This method also allowed for the integration of automation and infrastructure as code (IaC) practices, which would further enhance the efficiency and manageability of the new environment.
Microsoft Azure Virtual Desktop (AVD)
Following a thorough evaluation of various options, Capgemini recommended implementing Microsoft’s Azure Virtual Desktop (AVD) solution to meet National Gas’s key requirements. AVD was identified as an ideal choice due to its robust security features, scalability, and cost-effectiveness. This solution provided a comprehensive platform for managing applications, data, and systems securely and efficiently, making it well-suited for the needs of developers and data scientists.
With AVD, National Gas could ensure that users had secure access to the cloud environment while maintaining control over data and application usage. The virtualization technology enabled the organization to deliver a consistent experience across different devices and locations, ensuring that users could work remotely without compromising security. Additionally, AVD’s integration with Azure’s security tools, such as MFA and PIM, provided an extra layer of protection, ensuring that only authorized users could access sensitive information and resources.
Implementation and Technological Integration
Automation and Infrastructure Deployment
The implementation process involved developing a fully automated solution to deploy infrastructure and single-session virtual desktops using Terraform (infrastructure as code) and DevOps pipelines. This automation was crucial in ensuring a consistent, efficient, and error-free deployment process, significantly reducing the potential for human error and speeding up the overall migration timeline. By leveraging infrastructure as code, National Gas could version control, audit, and manage its infrastructure in a way that was both reliable and repeatable.
Automation through Terraform and DevOps pipelines allowed for the rapid provisioning of resources, which was essential given the tight deadline for the divestiture. This approach also enabled the organization to make changes quickly and confidently, knowing that the automated processes would maintain consistency and compliance. By incorporating these automation tools, National Gas could streamline its operations, reduce manual intervention, and focus on delivering high-quality services to its users.
Azure Security Tools
To ensure a secure separation of applications and infrastructure between National Grid and National Gas, Capgemini integrated several Azure security tools. These included location awareness, conditional access, multifactor authentication (MFA), and Privileged Identity Management (PIM). These tools provided robust security measures to protect data integrity and ensure compliance with industry regulations while allowing secure access to the cloud environment.
The integration of Azure security tools was a critical component of the migration strategy, helping to safeguard against unauthorized access and potential threats. Location awareness and conditional access policies allowed National Gas to implement granular controls over who could access specific resources, based on their location and other factors. MFA added an additional layer of security by requiring multiple forms of verification before granting access, while PIM helped manage and monitor privileged accounts, reducing the risk of misuse or abuse.
Benefits and Outcome
Enhanced Security and Centralized Data
The implementation of Azure Virtual Desktop (AVD) provided National Gas with a secure and centralized environment for data and applications, significantly enhancing overall security. This centralized setup allowed the organization to manage different users, including developers, data scientists, and vendors, effectively. By consolidating data and applications into a single, secure environment, National Gas could better control and monitor access, ensuring that only authorized users had access to sensitive information.
Centralized data management also facilitated improved oversight and governance, making it easier to enforce security policies and track usage. This enhanced visibility allowed the organization to quickly identify and address any potential security issues, ensuring that the cloud environment remained secure and compliant with industry regulations. The combination of AVD and Azure security tools provided a robust solution that met the organization’s needs for secure, efficient, and scalable cloud infrastructure.
