Version Control & Collaboration Comparison

TDM Problem	The DevOps Solution	GitLab	GitHub
Automatically synchronize assets across different SCM providers?	EXTERNAL REPO MIRRORING	💚 Mirror branches, tags, and commits between GitLab and external repositories which is automatically updated.	💛 ⚠ Requires Plugins (Actions) which increases security risk and introduces technical support gaps.
Meet development requirements for SCM scalability and availability?	HORIZONTAL SCALING & PERFORMANCE TUNING	💚 GitLab Application components can scale out horizontally and run on separate nodes. GitLab offers performance monitoring and tuning of the GitLab Instance	💔 ⚠ Supports vertical scale only which Creates Bottleneck. No support for performance tuning.
Facilitate easy collaboration with designers?	DESIGN MANAGEMENT	💚 Upload design assets to GitLab issues and keep them stored in one single place, giving product designers, product managers, and engineers a way to collaborate on designs over one single source of truth.	💔 ⚠ Creates collaboration barriers between designers and extended team members
