Do I still need a VPN with cloud services?

For internal applications and databases, yes. For SaaS applications with their own security, VPN is not needed. Modern ZTNA alternatives can replace VPN for application access with better security.

Which VPN solution is best for small businesses?

Tailscale is excellent for small teams (free for up to 3 users). For site-to-site cloud VPN, use the cloud provider managed service. For larger teams, consider Cloudflare Access for zero-trust access.

Does VPN slow down internet speed?

Modern protocols like WireGuard reduce speeds by only 5-15%. Older protocols can have more impact. For most business applications, the reduction is not noticeable.
