Hemiptera plant. Phloem sap, which has a higher concentration of sugars and nitrogen, is under positive pressure unlike the more dilute xylem sap. Most of the Sternorrhyncha and a number of Auchenorrhynchan groups feed on phloem. Phloem feeding is common in the Fulgoromorpha, most Cicadellidae and in the Heteroptera. The Typhlocybine Cicadellids specialize in feeding on non-vascular mesophyll tissue of leaves, which is more nutritious than the leaf epidermis. Most Heteroptera also feed on mesophyll tissue where they are more likely to encounter defensive secondary plant metabolites which often leads to the evolution of host specificity. Obligate xylem feeding is a
SAP HANA which SAP calls "Tailored Data Center Integration (TDI)". HANA is certified to run on multiple operating systems including SUSE Linux Enterprise Server and Red Hat Enterprise Linux. Supported hardware platforms for on-premise deployment include Intel 64 and POWER Systems. The system is designed to support both horizontal and vertical scaling. Multiple cloud providers offer SAP HANA on an Infrastructure as a Service basis, including: SAP also offer their own cloud services in the form of: SAP HANA licensing is primarily divided into two categories.
