Chapter 6  The Cloud
                262
                                               Some of the SaaS products that Falcon could use are:
                                               •  Google Mail
                                               •  Google Drive
                                               •  Office 365
                                               •  Salesforce.com
                                               •  Microsoft CRM OnLine
                                               •  And many others …

                                               You already know what the first three SaaS offerings are. Salesforce.com and Microsoft’s
                                            CRM OnLine are customer relationship management systems, which you will learn about in
                                            Chapter 7.

                                            PaaS Services at Falcon Security

                                            With PaaS, Falcon leases hardware and operating systems in the cloud from the cloud vendor.
                                            For example, it can lease EC2 (Elastic Cloud 2, a PaaS product offered by Amazon.com), and
                                            Amazon.com will  preinstall either Linux or Windows Server on  the cloud hardware. Given
                                            that basic capability, Falcon would then install its own software. For example, it could install
                                            its own, in-house developed applications, or it could install other applications licensed from
                                            a software vendor. It could also license a DBMS, say, SQL Server from Microsoft, and  place
                                            it on an EC2 Windows Server instance. In the case of software licensed from others, Falcon
                                            must purchase licenses that permit replication because Amazon.com will replicate it when it
                                            increases servers.
                                               Some cloud vendors include DBMS products in their PaaS services. Thus, Falcon could
                                            obtain Windows Servers with SQL Server already installed from  the Microsoft Azure cloud
                                            offerings. That option is likely what Toshio was considering when he mentioned the $10 per TB
                                            per month.
                                               DBMS are also included in other vendors’ cloud offerings. As of May 2015 Amazon.com
                                            offers the following DBMS products with EC2:


                                             Amazon Relational       A relational database service supporting MySQL, Oracle, SQL
                                             Database Service (RDS)  Server, or PostgreSQL
                                             Amazon DynamoDB         A fast and scalable NoSQL database service
                                             MongoDB                 A NoSQL DBMS product that stores objects in JSON format

                                             Amazon ElastiCache      An very fast in-memory cache database service
                                             Amazon Redshift         A petabyte-scale data warehouse


                                               Finally, Falcon might use a CDN to distribute its content worldwide and to respond to leads
                                            generated from advertising as described in Q6-1.

                                            IaaS Services at Falcon Security

                                            As stated, IaaS provides basic hardware in the cloud. Some companies acquire servers this way
                                            and then load operating systems onto them. Doing so requires considerable technical expertise
                                            and management, and hence a company like Falcon is unlikely to do so.
                                               Falcon might, however, obtain data storage services in the cloud. Amazon.com, for example,
                                            offers data storage with its S3 product. Using it, organizations can place data in the cloud and
                                            even have that data be made elastically available. Again, however, an organization like Falcon
                                            would more likely use SaaS and PaaS because of the added value they provide.
