|Pros of Zabbix LTS vs. Standard Release||LTS Release||Standard Release|
|More suitable for large-scale enterprise environments||
New Zabbix LTS version is released every 1,5 years
New Standard release is out every 6 months, which requires upgrading every half a year. That could be troublesome for large business IT infrastructures
|Long-term support distribution for Zabbix customers||
5 years in total, consisting of 3 years of general, critical and security issues fixes (Full Support) and 2 additional years of critical and security issues fixes only (Limited Support)
6 months of Full Support and 1 additional month of Limited Support
Due to long-term support of critical and security issues, Zabbix LTS version is more stable and reliable
By no means is Zabbix Standard release not tested until it is fully stable and secure. But because of the more frequent release policy and much shorter Support duration, Zabbix Standard versions have less time for issues fixing
|Cons of Zabbix LTS vs. Standard Release|
|Earlier access to new features||
Zabbix LTS is released every 1,5 years, so, if you are monitoring large-scale enterprise environments and it is more suitable for you to upgrade to Zabbix LTS versions only, then you have to wait for 1,5 years to get access to new features that were developed throughout this period
Due to a 6-month release cycle of Zabbix Standard releases, you will get access to the latest developed features every 6 months
