The ease of use, it is very intuitive to set up new servers or even restart them with just one click. It also offers some nice features like auto-scaling for high availability purposes in case you are running multiple instances at once (which I haven't done yet). A bit expensive compared to other web application server products out there but if your budget allows then this product may be worth considering as well because they have been around since 2005 so their support has always kept me happy! If anyone's looking into hosting an online store that requires frequent restarts/server upgrades - go ahead give Lena a try first before making any decisions about choosing another platform! We were able handle all our website traffic without having downtime issues which was great when we had over 200k unique visitors per month during prime times such as Black Friday & Cyber Monday sales!!
