What about using the REHOST MIGRATION TO AWS?
What about using the REHOST MIGRATION TO AWS?
#Rehosting (lift and shift) is the process of migrating your on-premises application to the cloud without modifying it. This strategy is used mostly to migrate large-scale applications to satisfy specific business goals, such as launching a product in an accelerated timeline or leaving an on-premises data centre. The applications are rehosted on Amazon Elastic Compute Cloud (Amazon EC2) Windows instances that meet the requirements of the applications you migrate.

Rinnovamento dell'infrastruttura
La CompanyTS era solita esternalizzare quasi tutto a una società IT terza.
CompanyTS
(No Profit - 6 mln di fatturato annuo - media impresa - circa 200 dipendenti)
1ª proposta di riduzione costi e rinnovamento infrastruttura IT on-premises:
40.000 euro per 5 anni per 8 microserver HP gen 8 - fuori supporto dal 2021.
Questi server utilizzavano il 10% della CPU per tutta la settimana, e solo il venerdì raggiungevano l'80% per il backup - in cohousing.
Dopo aver ridotto i costi, internalizzando e ottimizzando l'infrastruttura, l'IT Manager, sapendo che il consulente terzo non poteva essere cambiato, concorda una riduzione dei costi previsti a circa 25.000 € per 5 anni.
E poi l'IT Manager ha deciso di dimettersi (per essere educati).
Che ne dite di usare la #migration #rehost su #AWS?
#Rehosting - #not #the #best #solution (#non #la #soluzione #migliore)
Il #Rehosting (lift and shift) è il processo di migrazione della tua applicazione on-premises sul cloud senza modificarla. Questa strategia è usata principalmente per migrare applicazioni su larga scala per soddisfare specifici obiettivi aziendali, come il lancio di un prodotto con tempistiche accelerate o l'abbandono di un data center on-premises. Le applicazioni vengono rehostate su istanze Windows Amazon Elastic Compute Cloud (Amazon EC2) che soddisfano i requisiti delle applicazioni migrate.
La non-profit può usufruire di 1000 crediti AWS per 89 euro all'anno.
Il costo del #rehost senza questi crediti sarebbe di € 9074,40
€ 9074,40 + (89*5 = 445) - 5000 = 4519,40 €
COSTI TOTALI RIDOTTI PER 5 ANNI #ON-#PREM #COHOUSING
25.000 €
COSTI TOTALI PER 5 ANNI CON #AWS + #AWSTechsoup?
4.519,40 €
Semplificato ma molto vicino alla verità.
