Memory (GiB) :64 +upgrade =128 (package=228, so auto upgrade to 228)
Price strategy = On-Demand Instances (ordering spike that happens in Apr, Nov and Dec period.)
Total =4,223.78 USD

● The benefits for cloud implementation
1. cost reduction
2. faster time to market
3. high scalability & elasticity
4. improve reliability
5. continually improving performance
6. better security
Cost Reduction
Pay as use
Less IT staff, less expensive
No need setting up expensive hardware and server
AWS provides a lot of free tier product, so customers can choose their favorite products from the free tier product
After becoming a customer of aws ,customer will enjoy some always free product, so there is no need to spend all the time for adding new product
No need to worry about capacity planning
Can add and remove capacity anytime to meet demands
This ease the migration process for existing application while preserving options for building new solution
With cloud implementation ,you can quickly scale workloads automatically in response to the fluctuating market demands.
good ，nood to add some more
