A Little Bit Tech
Thoughtful perspectives on technology, business and product — from strategic decisions and emerging ideas to hands-on projects and things learned along the way.
SD-WAN applies software-defined policy to wide-area network traffic, helping teams manage multiple links and application paths centrally. Its value depends on the underlay, security design, and operating model around it.
Start with the access, security, or operational problem. Map users, applications, identity, network paths, contracts, and ownership before choosing capabilities and piloting a controlled change.
MPLS and SD-WAN are not mutually exclusive. Compare the service commitments and traffic needs at each site, then decide whether MPLS, SD-WAN, or a hybrid design fits the requirement.
Secure Access Service Edge (SASE) is an architectural approach that brings WAN connectivity and security controls together for users, sites, and applications distributed across the internet and cloud. It is not one product, a synonym for SSE, or a requirement for every organisation.
In-depth reference architecture guides designed for senior developers, network engineers, and technology leaders.
