Planning is Paramount: Defining Your Needs and Goals
Before diving into the technical aspects, take the time to clearly define your business requirements and objectives. This will guide your SD-WAN implementation and ensure it aligns with your overall IT strategy. Ask yourself:
- What are your key performance indicators (KPIs)? (e.g., application performance, bandwidth utilization, latency)
- What are your security requirements? (e.g., compliance regulations, data protection policies)
- What is your current network infrastructure? (e.g., bandwidth capacity, existing security appliances)
- What are your budget constraints? (e.g., hardware costs, licensing fees, ongoing support)
Understanding these factors will help you choose the right Meraki MX appliances, configure your SD-WAN policies effectively, and measure the success of your deployment.
Choosing the Right Meraki MX Appliance
Meraki offers a range of MX security appliances to suit different network sizes and performance requirements. Carefully evaluate your bandwidth needs, the number of users, and the types of applications you’ll be supporting to select the appropriate model. Consider future growth and choose an appliance with sufficient capacity to handle increasing demand.
Optimizing Your SD-WAN Policies: Prioritizing Critical Applications
One of the key benefits of Meraki SD-WAN is its ability to prioritize traffic based on application type. Take advantage of this feature to ensure that critical applications, such as VoIP, video conferencing, and business-critical SaaS applications, receive the bandwidth and priority they need.
- Identify critical applications: Determine which applications are most important to your business operations.
- Create traffic shaping rules: Configure rules to prioritize traffic for critical applications and de-prioritize less important traffic, such as social media or streaming services.
- Monitor application performance: Regularly monitor application performance to ensure that your SD-WAN policies are effectively optimizing traffic flow.
Security Considerations: Implementing a Layered Approach
Meraki SD-WAN offers integrated security features, but it’s important to implement a layered security approach to protect your network from threats. Consider the following:
