Propose the most suitable architecture for a new IT infrastructure in accordance with the case study below. The potential solutions could be: upgrade and buy new hardware (on-premises) migrate to the cloud a combination of the two (hybrid) Background PW Limited is a South Australian winery which is expanding internationally. The company recently opened European and North American branches, and also has plans to open two new local offices per year. It's estimated the growth of the revenue can reach 20-40% annually. The winery currently has five main retail locations with showrooms and wine tasting facilities across three cities (Adelaide, Melbourne, Sydney). They also have a warehouse/office for a total of six physical sites. These physical sites are connected over a 1G network connection by a third-party provider which is reliable and robust, and will not be replaced as part of this project. PW WINERY Below is a list of the main IT systems running on the current infrastructure, which is about 4 years old: EST. 799 S 1x Primary Web Server (Server LAMP, i7,8Gb,1TB) (acts as the company website) 1x Backup Web Server (Server LAMP, i7,8Gb,1TB) (acts as the company website) which is mirrored from the first machine in case of an outage. There is no load balancing service installed on the web servers. Whenever an outage occurs, essentially someone plugs the network cable over to the backup server to keep the website running. 1 x Email Server Exchange (Server Win10, 7, 32Gb,8TB) 1x SharePoint Server for documents (Server Win10, i7, 32Gb,1TB) 1 Transaction Server (Server LAMP, i7,8Gb,1TB) (runs a sale management system, does credit card transactions + store transactions) 1x Customer Server (Server LAMP, i7, 12GB, 1TB) (runs a web-based CRM system, stores the customer records, number of loyalty points etc.) 1 x Backup NAS (10TB) 11 PCs (as direct connection points to the internal systems) 10 x Cash Register Computers (2 for each retail location) There is no central database server here. Each system has its own database on the same server. Challenge As the business grows overseas, it's an opportunity to review the company's current IT infrastructure capacity, and to decide how to reconstruct it to meet the needs for the foreseeable future. The current servers should be retired or upgraded once they reach five years of age. The company has received a quote for upgrading the current infrastructure in Australia (download the quote). Each physical office that is opened internationally is expected to cost an additional $10,000. The management board is also interested in what Cloud computing platforms can offer.

Decision from the board

After a thorough discussion on the recommendations you presented, the PW Winery Board has decided the following:

The on-premises systems will be phasing out after the hardware reaches the end of its lifespan.

The current systems will be gradually migrated onto the Cloud.

A prototype must be built before the migration starts, which will also be used as the instruction manual when migrating.

The new infrastructure will make full use of multi-region deployment for local (Australia) and the new markets (Europe and North America).

The on-premises infrastructure will be running side-by-side for a period of one year as a backup plan if anything goes wrong.

The prototype should also need to demonstrate the ability to up-scale to meet the business growth.

The Cloud infrastructure must be isolated in a private network to meet privacy and security regulations.
