week 4 Reyna The Shift from Local Networks to Cloud-Based Infrastructure

  Understanding the Shift from Local Networks to Cloud-Based Infrastructure Transitioning from a local physical network to a cloud-based network brings significant changes in how resources are accessed, managed, and secured. One of the most important concepts to grasp is the shared responsibility model. In traditional networks, the organization manages everything—from hardware to application security. In the cloud, however, the cloud service provider (CSP) handles the infrastructure, while the customer is responsible for data, identity, and configuration. Additionally, cloud networking introduces software-defined networking (SDN), which enables greater flexibility in traffic management and policy enforcement. Businesses must also consider network latency, bandwidth costs, and access controls when designing cloud architectures. These factors directly impact performance and security and must be evaluated carefully before migration. While the cloud offers scalability and efficiency, ...

week 3 reyna strategic planning

 This week’s material emphasized the importance of strategic planning when migrating to the cloud. One of the most critical first steps is assessing whether a resource should even be migrated. Not all applications or databases are suitable for cloud environments—some may perform poorly or face legal and compliance issues. That's why it’s essential to gather detailed baseline information, understand existing systems, and account for business continuity and security needs before initiating migration. The five key phases—assess, plan, migrate, validate, and manage—act as a roadmap for ensuring a smooth and efficient transition. These phases align closely with project management principles, highlighting the need for strong organizational oversight, risk mitigation, and communication throughout the process. Documentation from both the organization and the cloud service provider (CSP) plays a vital role in maintaining consistency and minimizing disruptions. By thoroughly preparing and f...

week 2 reyna Insights on Virtualization and Cloud Computing

This week’s focus on virtualization within cloud computing deepened my understanding of how virtual machines (VMs) function as logical versions of physical systems. The hypervisor plays a critical role in bridging the physical hardware with these virtual instances, managing resources efficiently while enabling multiple operating systems to run on a single host. I found the concept of virtual NICs (vNICs) particularly interesting, as they illustrate how networking adapts in virtual environments to maintain connectivity between VMs and external systems. Another key takeaway was the process of VM migration, especially in the context of cloud adoption. Migrating VMs allows organizations to transition workloads seamlessly, supporting scalability and flexibility. The availability of various tools simplifies this process, making cloud deployment more accessible. Overall, virtualization is foundational to cloud computing, enabling resource optimization, isolation, and easier management, which...

week 1 introuduction

 Hello everyone, and welcome to my IT blog! My name is Johnny Reyna, and I’m currently pursuing a degree in Information Technology. I’ve always been fascinated by how technology continues to transform the way we live and work, and I’m excited to share my learning experiences here as I dive deeper into the world of cloud computing. This blog marks the beginning of my journey into Introduction to Cloud Computing —a course that promises to explore how cloud-based technologies are revolutionizing the IT industry. While I’m still building my hands-on experience, I have a growing understanding of how cloud services like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) allow businesses to operate more efficiently and scale with ease. What really excites me about cloud computing is its flexibility, cost-effectiveness, and accessibility. In today's fast-paced environment, the ability to deploy resources on demand and support global operat...
