Disadvantages

Cost of implementation;Larger scale implementations may require training, planning, and certifications. Certain CMSs may require hardware installations. Commitment to the software is required on bigger investments. Commitment to training, developing, and upkeep are all costs that will be incurred for enterprise systems.^[10]

Cost of maintenance

Maintaining CMSs may require license updates, upgrades, and hardware maintenance.

Storage Volume

Volume of files may be large in HTML-based systems. A site that contains many files leaves itself open to errors. For example, a client updating the site may create errors; large amounts of files can cause issues with updating. Trying to find the right file may take time, and may be hard to find.

Latency issues

Larger CMSs can experience latency if hardware infrastructure is not up to date, if databases are not being utilized correctly, and if cache files that have to be reloaded every time data is updated grow large.Load balancing issues may also impair caching files.

Tool Mixing

Because the URLs of many CMSs are dynamically generated with internal parameters and reference information, they are often not stable enough for static pages and other Web tools, particularly search engines, to rely on them.
