 Building a Resilient Hybrid Cloud: Connectivity, Management & Troubleshooting

As more organizations migrate to the cloud, many discover that the hybrid cloud—a blend of on-premises infrastructure and cloud services is not just a transitional phase, but a long-term strategy.

Why? Because hybrid environments offer the best of both worlds: the scalability of the cloud and the control of on-prem data centers. But to make this approach work, seamless and secure connectivity between locations is absolutely critical.

This week, I dove into key strategies and technologies that support successful hybrid cloud deployments from connection types to troubleshooting. Here's what I learned:

Connecting On-Prem to the Cloud: 3 Options

Your hybrid cloud journey starts with choosing how to connect your environments. Three primary options exist, each with its own pros and cons:

  1. Public Internet VPNs

    • Easy to deploy

    • Cost-effective

    • Relies on internet bandwidth and encryption

    • Good for small-to-mid workloads or non-critical traffic

  2. Direct Connections (e.g., AWS Direct Connect, Azure ExpressRoute)

    • Offers high bandwidth and low latency

    • More secure than public internet

    • Ideal for high-performance enterprise needs

  3. Colocation Facilities

    • Houses your equipment closer to cloud infrastructure

    • Reduces latency

    • Simplifies network architecture and improves reliability

Your choice should reflect your organization's performance, compliance, and cost requirements.

Extending Networks with VLANs & VXLANs

As your hybrid network grows, traditional tools can’t always keep up.

  • VLANs logically segment your internal network

  • VXLANs extend segmentation across data centers and cloud regions using encapsulated traffic

These technologies let you stretch your enterprise architecture across locations while preserving policy, security, and performance boundaries.

Managing Addressing & Traffic in the Cloud

Once the connection is live, managing network traffic efficiently is the next hurdle. Here's what makes a difference:

  • DHCP in the Cloud: Automatically assigns IPs to cloud resources

  • Cloud DNS Services: Simplify naming and service discovery

  • Load Balancing: Optimizes traffic distribution, increases uptime

Cloud-native tools like AWS Elastic Load Balancer and Azure Load Balancer offer features like sticky sessions, health checks, and global distribution.

Troubleshooting in Hybrid and Multi-Cloud Environments

Good news: many traditional troubleshooting tools still apply!

  • Tools like ping, traceroute, and packet capture still play a vital role

  • Cloud monitoring tools like CloudWatch, Azure Monitor, and Sumo Logic add cloud-native visibility

  • Always consider cloud-specific factors like ephemeral IPs, dynamic scaling, and shared responsibility

In short, the troubleshooting mindset stays the same, but the environment demands new awareness.

 Final Thoughts

Hybrid cloud isn’t a detour it’s a destination for many organizations. To make it successful, IT teams must prioritize:

✅ Secure, performant connectivity
✅ Smart address and traffic management
✅ Reliable troubleshooting with both legacy and cloud-native tools

Mastering these foundations leads to smoother deployments, higher availability, and better ROI.

Let’s keep learning, testing, and building smarter networks

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...
