IT mapping refers to the process of creating a visual representation of an organization’s IT systems, components, and relationships between them.
In this article, we will share with you why IT mapping is critical for managing your Cloud environment and discuss the best practices and strategies for dependency management in the Cloud.

What Is IT Infrastructure Mapping?
The goal of IT infrastructure mapping is to provide a comprehensive overview of an organization’s technology landscape and to help identify interdependencies and potential risks. It can also be used to plan and manage IT projects, optimize resource utilization, and improve security and resilience.
IT infrastructure mapping typically involves creating diagrams and visualizations of network topology, server and storage configurations, applications, and data flow. This information can be used to support IT planning and management, incident response and recovery, and compliance and regulatory requirements. Understanding an organization’s IT infrastructure is essential when moving to the cloud.
How Do Application Dependencies Impact Cloud Migration?
Application dependencies impact cloud migration in several ways. Dependencies can determine which applications can be migrated together and in what order, as well as which applications are required to support other applications in the migration process.

Understanding these dependencies is critical when planning a cloud migration, as it helps to ensure that the migration is smooth and that all of the applications and systems continue to work as expected.
Managing dependencies
Dependency management is the process of identifying and managing the relationships between different components of an application or system. It is concerned with understanding what components depend on each other, and how changes to one component can affect others. In the context of cloud migration, dependency management is important because it helps to ensure that the dependencies between applications and systems are properly accounted for and managed during the migration process.
When migrating applications and systems to the cloud, it is essential to understand and manage the dependencies between these components. This is because the dependencies can determine which applications can be migrated together and in what order, as well as which applications are required to support other applications in the migration process. If these dependencies are not properly accounted for and managed, the migration process can result in disruptions and downtime, and the applications and systems may not work as expected in the new cloud environment.
How IT mapping helps in the migration process
IT mapping makes dependency management easier because it visualizes the dependency tree, allowing stakeholders to more readily understand the dependency landscape and plan the migration process. This is especially useful when there are unclear or hidden dependencies.
IT infrastructure mapping is important when planning a hybrid or multi-cloud deployment because it provides a comprehensive view of an organization’s technology landscape, including the relationships and dependencies between different applications and systems. This information is essential for developing a comprehensive migration plan and for rebuilding the dependency tree in the new cloud environment.

An IT infrastructure map also helps to identify potential issues and risks associated with the migration, as well as to ensure that the necessary resources and connectivity are in place to support the new cloud environment.
Best Practices and Strategies for Dependency Management in the Cloud
Let’s discuss the set of best practices and strategies for dependency management, including version pinning, vulnerability scanning, signature verification, and the steps that you can take to reduce your risks and have dependency management in the cloud under your control.
#1 – Use Version Pinning
Version pinning is a practice in software development that involves specifying the exact version of a software component or library that an application should use, rather than relying on the latest available version. By pinning the version of a component, developers ensure that the application will continue to work as expected, even if newer versions of the component are released.

In the context of cloud migration, version pinning facilitates dependency management by ensuring that the dependencies between applications and systems are accounted for and managed during the migration process. By specifying the exact versions of components and libraries that an application should use, teams, can ensure that the application will continue to work as expected in the new cloud environment.
#2 – Implement Signature and Hash Verification
Signature and hash verification are security best practices for ensuring the authenticity and integrity of software components and libraries in the cloud. They are used to confirm that the components and libraries being used are unaltered and have not been tampered with. Combining both types of verification provides an added layer of security and helps mitigate the risks associated with application and service dependencies.
Signature verification involves using digital signatures to confirm the authenticity of software components and libraries. The signature is generated by the software publisher and is verified by the recipient to ensure that the software has not been altered.

Hash verification involves generating a unique fingerprint, or hash, of the software component or library and comparing it to a known, trusted value. If the hash of the component or library being used matches the trusted value, it confirms that the component or library is authentic and has not been altered.
#3 – Keep Public and Private Dependencies Separate
Mixing public and private dependencies in the cloud can create security risks and increase the likelihood of a dependency confusion attack. Dependency confusion attacks occur when an attacker injects malicious code into a public library that is being used by an application. The attacker’s code is then executed in the context of the application, allowing them to gain access to sensitive information or take control of the application.
By avoiding the mixing of public and private dependencies, organizations can reduce the risk of dependency confusion attacks and better control the security of their applications and systems in the cloud. This can be achieved by:
* Using a private repository for private dependencies: This repository is not accessible to the public, ensuring the dependencies are secure and cannot be used by other applications or systems.
* Verifying the authenticity of public dependencies: Use digital signatures or hash verification to ensure that the dependencies are authentic and have not been tampered with.
* Keeping dependencies up-to-date: Regularly update dependencies to ensure that they are the latest, most secure versions.
# 4 – Vulnerability Scanning
Vulnerability scanning is the process of automatically testing an application or system for known vulnerabilities and security weaknesses. It is used to identify security risks and to help organizations secure their systems and applications. This is important because vulnerabilities in these components and libraries can result in security risks that can be exploited by attackers.

For example, a vulnerability in a library used by an application could allow an attacker to compromise the security of the application or access sensitive information. By regularly scanning the components and libraries that an application depends on for vulnerabilities, organizations can identify and address these risks before they can be exploited.
Automated scanners make this process much easier. Regular vulnerability scans both before and after cloud migration can help identify zero-day attacks and keep the organization’s security profile up to date.
Conclusion
IT mapping is a critical component of effective cloud management. By creating an accurate map of your IT infrastructure, you can better understand the relationships between your systems, applications, and data, as well as the dependencies that exist between them. This information is essential for making informed decisions about cloud migration and for ensuring the success of your hybrid or multi-cloud deployment.
IT mapping can also help to improve the security and reliability of your applications and systems by enabling you to identify and mitigate potential risks and vulnerabilities, and by ensuring that you have the necessary resources and processes in place to manage your cloud environment effectively.
