A Cloud Access Security Broker (CASB) acts as a gatekeeper between your company’s endpoints and the multiple cloud services they use, and is positioned on the network perimeter. CASB software allows your company to extend your security policies to SaaS applications such as O365, Salesforce, Dropbox, and IaaS platforms such as Azure or AWS. A CASB simply helps a business secure communications end-to-end from cloud to device and vice-versa, regardless if the device is managed or unmanaged, from any location or any user.
In addition, modern BYOD policies can leave businesses staring liabilities in the face as employees begin to use cloud services without the IT department’s knowledge. This so-called ‘Shadow IT’ leaves data in the dark. Businesses have a responsibility to keep track of sensitive data, and with GDPR around the corner there’s no room for complacency. CASB can help enterprises make a compliant move to the cloud.

One of the most important aspects of placing your computers on Azure is the ability to connect to them using the Remote Desktop Protocol (RDP) to your manage your Windows-based virtual machines (VM). The issue with RDP can be with the Remote Desktop service on the VM, the network connection, or the Remote Desktop client on your host computer. We will attempt to guide you through some of the most common methods to troubleshoot and resolve common RDP connection issues.
The steps are displayed in the general order, but you should try reconnecting to the VM after each troubleshooting step.

Microsoft is selling an appliance named StorSimple, that can be used for archiving files, a network backup target, or even as a file server. Microsoft bought the company named Xyratex, a former subsidiary of Seagate, to acquire this solution. This appliance was originally not very useful, because:
- It shared storage via iSCSI only so it didn’t fit well into a virtualization stack, especially Hyper-V which has moved more to SMB 3.0.
- The file storage engine that decided which files stayed local vs. were moved to the Azure cloud was almost useless.
- The physical appliance required space in your server rack, when virtualization is the focus for most solutions.
- While the box was free, it did require a purchase of an enterprise agreement and paying for moving files out of Azure as some files were accessed.
Microsoft has improved StorSimple over the years and now the product is much more useful.

For most companies, maintaining a large IT presence implies large capital expenditures and a non-trivial amount of accounting and record-keeping to track depreciation, tax considerations, and so forth. When you purchase the hardware and the software, they become yours (in every sense of the word) and your long-term responsibility. The traditional model of enterprise computing is a capital-intensive function that requires expensive data centers (electricity, air conditioning, servers, networks, storage, etc.) and operations staff (hardware swaps, networks, backups, OS updates, upgrades, etc.) to keep it all running effectively. With an on-premises data center, you must plan and provision for maximum utilization, which is financially inefficient.
The appeal of cloud computing includes the ability of enterprises to pay for only what they use. If demand decreases and you no longer need the assigned capacity, you can turn off systems and you are no longer charged for those systems. Since the cloud is a subscription-based model, it is an “operating expense” model. Computing becomes a service for which businesses are billed a monthly charge that is metered by actual usage. The more (compute, network, and storage resources) that you use the more expensive your monthly bill. The less you use, the less you will be charged.
Another way to save money is cloud operations frees your enterprises of the costly tasks of system backups, routine network maintenance, software patches, etc. because you cloud provider can handle these tasks.
Most IT organizations find wide variations in system utilization. Some applications are seasonal and other applications run for a short period of time before being shut down. You might have other applications that are simply unpredictable and you can’t apply a cost saving model.
Building your server infrastructure in a cloud environment can save your business money and allow for greater innovations for less money.
Just some quick tips for building a SQL Server instance on Azure virtual servers.
||DS3 or higher for SQL Enterprise edition.
DS2 or higher for SQL Standard and Web editions.
||Use Premium Storage. Standard storage is only recommended for dev/test.
Keep the storage account and SQL Server VM in the same region.
Disable Azure geo-redundant storage (geo-replication) on the storage account.
||Use a minimum of 2 P30 disks (1 for log files; 1 for data files and TempDB).
Avoid using operating system or temporary disks for database storage or logging.
Enable read caching on the disk(s) hosting the data files and TempDB.
Do not enable caching on disk(s) hosting the log file.
Important: Stop the SQL Server service when changing the cache settings for an Azure VM disk.
Stripe multiple Azure data disks to get increased IO throughput.
Format with documented allocation sizes.
||Enable database page compression.
Enable instant file initialization for data files.
Limit or disable autogrow on the database.
Disable autoshrink on the database.
Move all databases to data disks, including system databases.
Move SQL Server error log and trace file directories to data disks.
Setup default backup and database file locations.
Enable locked pages.
Apply SQL Server performance fixes.
||Back up directly to blob storage.
