CONNECTING AND SECURING ON-PREM NETWORK TO CLOUD INFRASTRUCTURE
Keywords:
Hybrid Cloud Connectivity, Secure Cloud Networking, VPN, Sd-Wan, Cloud Security Best PracticesAbstract
As more businesses use hybrid cloud models, it's important to make sure that on-premises networks can connect to the cloud quickly and safely. This article talks about different ways to connect, such as Software-Defined Wide Area Networking (SD-WAN), Virtual Private Networks (VPNs), and dedicated private links. It talks about the pros and cons of each method and how important it is to use strong security measures like tracking, encryption, multi-factor authentication, and micro-segmentation. When choosing a connectivity option, the article stresses how important it is for businesses to carefully think about their needs and things like bandwidth, latency, reliability, and cost. It also shows how managed security service companies are becoming more and more important for helping businesses plan, set up, and run safe cloud connectivity solutions.
