{% hint style="info" %} The Subscription is Quantity-based, also known as resource-based. Subscriptions allow consumers to subscribe to a plan and specify the number of units at the time of subscription. {% endhint %} Subscriptions are monthly billed and can be updated at any time. BUT when a Organization updates its subscription, it will be billed for the proration of the current used % of the month and then the billing will continue with the percentage of the rest of the month with the new resources. Lets see some examples: Case 1: * Org example1 starts the subscription on 1th April 2024 with 10 resources * after 15 days they realized Cloud Plans is suitable for more servers and decided to upgrade the Subscription to 100 In this Case 1, Org example1 starts with a estimated billing of ($5,99 x 10) $59,9, and in the 15th April it will be billed with $29,99. In the 30th April it will be billed with ((($4.19 x 100) / 30) x 15) $209,50. Now imagine your average instance is a t3.large / t3.medium ... t3.medium -> * Normal monthly costs: $30,96 * With Cloud Plans: * Cloud Plans costs in the Case 1: $2,99 + $2,09 = 5,08 $ * 86h instance costs: $3,59 * Total Costs: $8,67 * Savings: $30,96 - $8,67 = 22,29 $ -> Saves 71,99% over the NO Cloud Plans option * Now in the above example we have 10 instances first 15 days and then 100: * First 15 days: * NO Cloud Plans: (30,96/2) \* 10 = 154,8 * With Cloud Plans: (8,67/2) \* 10 = 43,35 --> You saves $111,45 in 15 days * Last 15 days: * NO Cloud Plans: (30,96/2) \* 100 = 1548 * With Cloud Plans: (8,67/2) \* 100 = 433,5 -> You save $1114,5 in 15 days * Full Month: you save $111,45 + $1114,5 = **$1225,95** (including CP costs) t3.large -> * Normal monthly costs: $60,12 * With Cloud Plans: * Cloud Plans costs in the Case 1: $2,99 + $2,09 = 5,08 $ * 86h instance costs: $7,18 * Total Costs: $12,26 * Savings: $60,12 - $12,26 = 47,86 $  $ -> Saves 79,6% over the NO Cloud Plans option * Total savings in Case 1: * No Cloud Plans Costs: (($60,12 \* 10) / 30) \* 15 = 300,60 $ + (($60,12 \* 100) / 30) \* 15 = 3006; 300,60 + 3006 = 3306,6 * With Cloud Plans Costs: ((12,26 \* 10) /30) \* 15 = 61,3; ((12,26 \* 100) /30) \* 15 =613 -> 61,3 = $674,3 * Full Month Savings: 3306,6 - 674,3 = **$2632,3** (including CP costs)
